The Big List of Group Costume Ideas

Posted on June 26, 2015 by Lou

Fun, Cool & Just Plain Great Group Costume Ideas!

Bavarian Beer Wenches - Group Costume Idea for Women

Bavarian Beer Maid Costumes

If you want to dress up as a group for Halloween this year (or any other fancy dress event for that matter) then I’ve got some great ideas for you. There’s something really fun with having a group of you dressed as a group and it can make for a great night out for everyone.

Inspiration for group costumes come from just about anywhere – musical groups, television shows, films even everyday life. The hardest thing is to get everyone to agree on the costume idea which is where I come in. I’ve compiled a list of group costume ideas that you can all look through and see if one of them stands out to you all as the perfect one.

Group Costume Ideas Based on Music Groups

There are some music groups/bands who are instantly recognizable and so make a great idea for a group costume, here are some of the ones that spring to mind-

Abba – The 70s pop group were known for their costumes and if you feel like turning into ‘Dancing Queens’ for the night then this is a cool costume idea for a group of 4 (it should be 2 couples, but I’ve seen a few male Agnetha and Frida’s in my time and they’ve been quite funny!).
Kiss – Crack out the face paint and the platform boots for this group costume idea, another great costume idea for a group of four.
The Beatles – The fab four are another cool group costume idea and if there’s 8 of you you could try a ‘Beatles through the ages’ theme with their basin hair cuts and suits through to the longer haired Sergeant Pepper days.
The Spice Girls – For five girls you know that you want to dress up as the Spice Girls, it’s what you ‘really, really want’! This is another fun group costume that is instantly recognizable.
The Village People – This six piece group are one of the groups that several generations recognize straight way and are likely to start people singing earwig disco songs such as Macho Man and YMCA!
Z Z Top – This Texan three piece group make another cool costume idea for a small group and you can see how to get the look below.

ZZ Top Costume Ideas

Perfect for a Small Group of 3

This Texan trio are best known for the beards that two of their members sport – the third member has Beard as a surname so doesn’t actually need to have one!

You actually have a lot of latitude with what you can wear to accompany these beards as ZZ Top have been around for quite a while and have been seen in a few different outfits over that time.

The most well known look was probably the one that coincided with their album Eliminator hitting the mainstream charts for that look you want the two bearded members of the band to be wearing black suits with the non-bearded Mr Beard wearing black trousers with a long black duster coat. All three of them should be sporting hats similar in shape to the one featured in the image below along with some black sunglasses.

Of course another look that their fans are very familiar with sees them in jeans and leather jackets along with either hats (again like the one pictured) or skull caps and their sunglasses.

Personally I think as long as you all wear sunglasses and two of you sport these beards (and to really ‘sell’ it a couple of guitars – Frank Beard is the drummer so don’t have him with a guitar!) it won’t matter what else you wear everyone will know you’re ZZ Top.

Group Costume Ideas Based on Television Shows

Some of our favorite television shows have given us some great ideas for group costumes including these –

Care Bears
Game of Thrones
Sesame Street
Star Trek
Teenage Mutant Ninja Turtles
Teletubbies
The A-Team
The Addams Family
The Big Bang Theory
The Brady Bunch
The Flintstones
The Munsters
The Muppets
The Mystery Inc Crew (aka Scooby Doo & friends)
The Simpsons

You’ll note that some of these contain links which will take you to another webpage that is dedicated to those particular costumes. I don’t have them all covered yet, but I’m hoping to be able to get links for all of these group costume ideas in time.

Teletubbies Costumes

You used to be able to purchase these Teletubbie costumes in a set of four which was really cool, but I’m having trouble sourcing a set at the moment so you have to purchase your favorite teletubbies separately.

Group Costume Ideas Based on Movies

Movies are another source of inspiration when it comes to thinking of group costume ideas, from classic movies to more modern ones that are certainly a lot of them to think about. Here are a few that spring to mind

300 (Spartans – see below for a costume idea)
Sucker Punch
Grease
The Avengers
The Wizard of Oz
The Suicide Squad
Ghostbusters

More Group Costume Ideas

There are lots more ideas for group costumes that don’t belong in any of the categories above –

Alice in Wonderland Characters – Someone obviously has to be Alice and then it’s simply a case of choosing the best known characters until everyone in your group has a costume. The bigger the group the more less known the characters that will add to the ‘ensemble’.
Angry Birds – You can get all of the different Angry Birds characters in costume so it’s just a case of everyone choosing their favorites.
Batman, Robin & all the Villains – Make sure that you have Batman and Robin covered and maybe even Alfred and then simply add the villains until everyone in your group is covered – there’s certainly plenty of villains to choose from including the Penguin, the Joker, Poison Ivy etc. Don’t forget the Suicide Squad! Another great group costume idea.
Bavarian Beer Maids & Men – These costumes are also found under Oktoberfest costumes and can be a lot of fun to wear.
Crayons – You can get some great Crayola costumes (although these are designed for ladies) in various colors so if you all chose a different color you can say you’re a box of crayons, but you lost your box!
Ever After High School Pupils
Ghosts – You can dress up as a group of ghosts and create your very own haunting!
Green Army Men Figures
Guess Who ‘People’ – This is a costume that I’ve seen images of and is definitely in the diy Halloween costume column. If you need instructions check out Homemade Guess Who Characters.
Hip Hop Dance Crew – Whether you go with a Jabbawockeez Halloween costume, Remix Monkeys or a dance crew from any of the popular dance themed movies.
Lego Minifigures
M & Ms – You can actually buy sets of group M&M costumes or you could just buy/make the costumes yourselfs, just make sure you’re all different colors, the room won’t be big enough for two Reds for example!
Mickey, Minnie & Friends
Monster High Pupils – If you’re after this costume ideas for a group of young girls you can check out – MHS Costumes for Girls.
Oompa Loompas – From Willy Wonka’s Chocolate Factory the Oompa Loompas make a fun costume and I’ve even seen a group of people dressed up as them at an international rugby match in recent years – they certainly stand out on camera!
Pac Man – You can buy a set of group costumes (see below for one example) for this idea yourself – they’re available for sets of 5 or 6 and feature Pac Man himself along with the ghosts.
Snow White & the Seven Dwarfs
Tetris Blocks – This is a very cool costume ideas that is easy to make at home as it simply requires lots of cardboard boxes, paint and black electrical tape. There are lots of pages that show you how to make them online, here’s one of them – The Diary of Tetris.
The Smurfs
The Tudors – You can dress as a group of Tudor peasants or a group of Tudor aristocrats for a fun costume idea. If you wanted to you could also dress as famous Tudor people whether it’s Henry VIII and all six of his wives or all of the Tudor monarchs together is up to you!
The Wiggles – a pair of black trousers and different colored skivvies are all you need to be The Wiggles and if there’s more than four of you in the group then you can get one of you to dress up as Captain Feathersword, another as Dorothy the Dinosaur and just keep working through these favorite children’s characters until your group are all in fancy dress……..watch out though if you’re too good you might get booked for a child’s birthday party!
Winnie the Pooh & Friends

Pac Man Group Costume Set

This is a classic group costume idea for six people. Featuring Pac Man himself along with the four ghosts and one ghost that’s ready to be eaten!

The great thing about this costume idea is that all of the costumes are unisex so it really doesn’t matter what the make up of your group is – all male, all female or a mixed bunch.

I do love the idea of this costume as I’m an eighties girl at heart and Pacman has certainly become known as THE video game of the decade (in all honesty I preferred Space Invaders, but Pacman obviously had a better PR person behind them!!)

The Flintstones Fancy Dress Costumes

Posted on August 25, 2013 by Lou

The Flintstones fancy dress costumes are a great idea for any fan of Fred Flintstone and his friends and family. I can’t think of a better crowd than the Flintstones and Rubbles to dress up as for a group costume idea, yabba dabba doo!

One of our friends actually dressed up as Barney Rubble many moons ago and did a really good job of it. I haven’t actually seen any of our friends dress up as Fred and Wilma yet though so it could be a great idea for hubby and I this Halloween – what do you think?

In a hurry? Shop The Flintstones Halloween Costumes Now!

Enough yapping about the Flintstones, let’s look at their costumes…..

Adult Fred Flintstone Costume

The Flintstones’ patriarch is constantly scheming, although he has a big heart so if this sounds like you then check out the costume selection below.

There’s really no mistaking who you are with this outfit whether you’re saying yabba dabba doo or not!

The Flintstones Fred Flintstone Costume,The Flintstones Fred Flintstone Costume

Wilma Flintstone Fancy Dress Costume

Fred’s long suffering wife Wilma is also instantly recognizable to everyone who grew up watching The Flintstones on television and if you’re looking for a great idea for a couples costume then Fred and Wilma Flintstone certainly make a fun costume idea.

There are a couple of costumes available to buy for Wilma as you can see below –

The Flintstones Wilma Flintstone Costume The Flintstones Wilma Flintstone Costume

Pebbles Flintstone Halloween Costume

Fred & Wilma’s only child was a daughter named Pebbles and you can get a fun Pebbles costume below-

Pebbles Flintstone Costume

So before you can say yabba dabba doozie! You can dress up as Pebbles and be part of a Flintstones group costume idea. If you’re after a family costume then there are children costumes available as well.

Barney Rubble Halloween Costume

You can’t really have Fred without his best friend Barney who would always do ‘whatever you say, Fred’ before they both landed up in trouble! I do have to issue a warning on this costume though …….. a friend of ours dressed up as Barney Rubble for a fancy dress party more moons ago than I care to say and he is still being called Barney by everyone. The look was a little too convincing methinks.

The Flintstone’s Barney Rubble Deluxe Costume The Flintstones Barney Rubble Fancy Dress Costume

Betty Rubble Halloween Costume

Great friends with Wilma Flintstone, Betty has to put up with Barney being regularly led astray by Fred and she does so while still looking pretty in a stone age way –

Betty Rubble Halloween Costume

This costume even includes the wig so is perfect if you want to dress up as Betty Rubble. I must admit I always preferred Betty’s blue dress to Wilma’s wardrobe. The shoes featured above aren’t included but then I don’t recall seeing her ever wear shoes on the cartoon so I’d go barefoot.

There are a few other options for Flintstone costumes such as Dino the Flintstone’s pet or Bamm Bamm the Rubble’s son, but I think I’ve covered the main Flintstones in this post. Of course you may decide that you don’t want to buy a ready made costume and the Flintstone’s costumes are quite basic which makes then a great idea for a diy costume.

Halloween Costume Ideas – Costumes Beginning with P

Posted on March 23, 2013 by Lou

The classic ‘P’ costume has to be pirates and let’s face it this is a costume that never gets old.

Costumes Starting with the Letter P

Paddington Bear
Panda
Paris – Paris can take a variety of interpretations. It could be the city or the Paris who caused the Trojan war on account of Helen of Troy. You could also go as Paris Hilton, the well-known socialite. Use a skimpy dress, a long blonde wig, and a small dog in a handbag to create that look.
Pauly D (Jersey Shore) – Whether you’re a fan of the Jersey Shore or of the Pauly D Project this is a cool Pauly D costume to wear. I must admit I haven’t seen either program, but they certainly have a lot of fans.

Pebbles -The Flintstones make great costume ideas for a fancy dress party and I’ve seen a number of Freds, Wilmas, Barneys and Bettys over the years, surprisingly I’ve never seen anyone dress up as Pebbles, but if you’re going to a P party it’s a pretty good choice

Costumes Beginning with F

Posted on October 15, 2012 by Lou

Fancy Dress Outfits Starting with the Letter F

If you’re looking for costumes beginning with F for a themed party then I’ve compiled a great list for you from Fred Flintstone to a French Maid.

I’ve compiled this page with a range of others as I used to attend alphabet parties in my 20s and they were so much fun. I read a few years ago that they were making a comeback so for those of you who draw a blank when you have to come up with ideas for costume party here’s your resource list

NOTE: As an Amazon Associate I earn from qualifying purchases – more information below

Cool Costumes Beginning with F

Fairy – a classic little girls costume, but there’s also costumes for grown ups as well – I especially think men can dress up as the tooth fairy after the Rock’s performance!
Fairy Godmother
Fame character – go back to the 80s with leg warmers, leotards and off the shoulder shirts
Fat B**stard – A character from Austin Powers, I seem to know a lot of people who enjoy talking like the Fat B**stard so I’m sure they’d love to dress up as him as well.
Father Christmas
Father Time – Wear long robes for this costume, some people depict him in white robes while others show him in black robes, what all costumes show is a big timepiece hanging around his neck.
FBI officer – wear the standard issue black suit and look like a fed or wear regular clothes and just flash your badge if you want to be an undercover agent, just don’t forget to talk into your watch and wear an ear piece.
Fester Addams aka Uncle Fester – Uncle Fester, the Addams Family hasn’t been on air for years and yet they’re all instantly recognizable.
Fiona (Shrek)
Fireman
Fisherman – you can dress up in yellow wet weather gear as though you’re a trawler fisherman or else you can wear waders and carry a bag with a few feathers on hooks on it (along with a fishing rod that is) and say you’re a trout fisherman.
Flamenco Dancer
Flamingo
Flapper – there are lots of different Flapper outfits to choose from as well as loads of fun accessories from headbands to long beads, boas or cigarette holders. I love the fashions of the 1920s which is why I love all of the flapper outfits. Check out a whole selection on this page – 1920s Style Flapper Halloween Costumes.

DC Comics Deluxe Muscle Chest The Flash

Flash (The) – This superhero has probably gained an even bigger success thanks to the small screen success of the Big Bang Theory where he’s one of Sheldon’s favorite fancy dress outfits.
Flight attendant
Florence Nightingale – a British nurse from the time of the Crimea war Florence Nightingale is seen as the founder of modern nursing. The outfit you need for this is very much like that of a Victorian scullery maid, including the cap, although rather than the white cotton caps worn by maids, Florence Nightingale’s one was more of a white lace cap. She was known as the lady of the lamp as she would check on her patients at night so getting a lamp to carry would be a great prop for this costume.
Flower – A flower is a great costume for if you want a DIY project. Simply wear green for the stem, add face paint the color you want the middle of the flower head to be and then attach the petals around your face (I would use a piece of elastic to run under your chin and over your head. The petals could be made from tissue paper to cardboard or even fabric.
Flower Pot Men – Bill and Ben from the old British cartoon.
Flower Power Hippie – embrace your inner 60s child with a ‘peace man’ attitude and flowers in your hair! A little outside of the box thinking again for a cool costume idea.
Fly
Flying Monkey from Wizard of Oz
Football – I’ve actually seen costumes for sale for both an NFL football and a soccer ball, both of which do look like a bit of fun.
Footballer – American footballer from your favourite team or a soccer player the choice is yours.
Fork – I have seen a fork costume which I think is just priceless

Fortune Teller Costume

Fortune Teller
Fox
Fox Hunter
Foxxy Cleopatra (Austin Powers)
Frank n Furter (Rocky Horror Picture Show)
Frankenstein
Frankenstein’s Bride
Frankie Stein – a Monster High costume idea, Frankie Stein was one of the original characters from the range.
Fred (from Scooby Doo) – Although Fred wasn’t my favourite Scooby character he is still from a cartoon that I loved growing up. It really seems to have struck a chord across generations as my father loved it, I loved it and my daughter loved it!
Fred Astaire
Fred Flintstone – The main character from the lovable Hanna-Barbera cartoon, The Flintstones.
Freddie Mercury
Freddy Krueger
French Maid
Frenchie (from Grease)
Friar Tuck
Frodo Baggins – a hobbit from Lord of the Rings
Frog
Fruit – there’s lots of different fruit costumes from apples to limes and more so you can just dress up as your favourite and if anyone says that oranges start with O, you can simply tell them you’re Fruit which starts with F …….. and then start planning an O party so you can re-use your costume!
Fuzzy Dice

If you’re after a costume that begins with another letter of the alphabet then I’ve got you covered with that too, simply check out my a-z of costumes page.

Back to the letter F and which costume idea is your favorite?

Costumes Beginning with B

Posted on July 23, 2012 by Lou

If you’re looking for some costumes beginning with B then you’re in the right place! If you saw my post a couple of weeks ago you’ll know we looked at costumes beginning with A which is why I thought it would be a great idea to do costumes beginning with B today and boy are there a lot to choose from.

We have all different types of fancy dress ideas from Bees, Bananas, Ballerinas and so much more to choose from. Let’s check them all out.

NOTE: As an Amazon Associate I earn from qualifying purchases – more information below

List of Costumes Beginning with B

Baby – all you need is to make what looks like an oversized diaper and a large baby bottle and you’re good to go. Alternatively, you can actually buy baby costumes that consists of a large stretch and go (much warmer for winter parties or Halloween.
Baby Doll – Baby Doll is one of the stars of the cult movie Sucker Punch and when I saw the movie I just knew that these costumes would be a hit! Baby Doll isn’t the only character that begins with B, there’s also Blondie as well and you can check them both out on my Sucker Punch Costumes post.
Baby Spice – The Spice Girls may no longer be together, but they were a force to be reckoned with and their costumes are still instantly recognizable. You can check out the Baby Spice costume on my Spice Girls Costumes post.
Ballet Dancer – a leotard, tutu and ballet slippers are all you need for this costume to work.
Ballroom Dancer – if you’re going to the event as a couple you can dress up as ballroom dancing partners, one in a suit, the other a ballgown and make sure that you have numbers on your back for the judges to score you.
Banana – the banana costumes that are available to buy are a really fun costume that draws everyone’s attention, although I have been known to ask people wearing such costumes if they can turn into a banana daiquiri for me……..I’m probably not the first person to ask that which could become tiresome!
Bandido
Bank Robber
Barbarella
Barbie
Barney – everyone’s favorite purple dinosaur, make sure you know a few of Barney’s songs if you choose this outfit!
Barney Rubble – Who doesn’t love the Flintstones? I know most people think of Fred and Wilma when the Flintstones are first mentioned, but I do have a soft spot for Barney myself! I feel I should add a warning with this costume….a friend of ours attended a fancy dress party about 20 years ago dressed as Barney Rubble and is still called Barney by just about our entire circle of friends! I’m sure that’s an isolated case though
Barney Stinson – If you’ve ever watched How I Met Your Mother you’ll know that the star of the show (in my opinion anyway) is Barney Stinson and it just so happens to start with the letter B! Barney Stinson coined the phrase ‘suit up’ and all you need to dress up as Barney is to dress in a suit and tie and memorize a few Barneyisms to sprinkle through your conversations throughout the night………oh and you’ll need short, tidy hair!
Barrister – black robes and a wig will make you look quite distinguished, but I’d make sure to add a big law book and a pair of glasses to really pull off this costume idea.
Bart Simpson – an absolutely classic costume
Bass Head Trophy – when I first came across this costume online I absolutely fell in love with it and think it’s one of the best B costumes around, check it out below.
Bat
Bat Girl
Batman

Costume Accessory: Trophy Head Bass Mask Women’s Dc Comics Superhero Batgirl Bodysuit Batman The Dark Knight Rises Batman Costume

Baywatch – you can get official Baywatch costumes for both male and female lifeguards, both are equally recognizable to any fan of the show.
Bear
Beast – from Beauty and the Beast fame, you could come on your own or with a partner dressed as Belle for the ultimate ‘B’ list couple!
(The) Beatles – There are a number of different costumes available of the Beatles from their tidy haircuts and suits days to the Sgt Pepper days, a great group costume idea.
Bee
Beefeater – did you know that the Beefeaters were first formed in Tudor times and that their costumes haven’t really changed in all of that time? My Tudor costume page actually features one for you.
Beer – always a favorite amongst my hubby’s friends, but there are actually quite a few different beer options available to choose from.

Rasta Imposta Beer Pint Costume, Gold, One Size Rasta Imposta Lightweight Beer Bottle Costume FunWorld Men’s Beer Keg Costume, Silver, One Size

Beer Wench – for anyone that’s attended Oktoberfest these are the ‘maids’ that are carrying your beers to you.
Beetlejuice – a classic 80s character, if you dressed up in this suit anyone who’s seen the movie would instantly know who you were and what a fun costume it is too!
Bellboy
Belle – If Belle is your favorite Disney princess then this is the excuse you need to dress up as her, alternatively this could be a great couples costume with the Beast.
Belly Dancer – This is a lovely costume for a female with a great figure OR a man who’s up for a laugh……imagine one of the guys you know wearing this it would be the talk of the party, but you’d need a confident person to carry it off.
Ben Hur
Benedictine Monk
Betty Rubble – Barney’s lovely wife Betty is a lovely costume and if you’re going to a party as a couple then you could go as Barney and Betty Rubble.
Beyonce
Big Bad Wolf – Fancy being the bad guy at the party? The big bad wolf is the biggest bad guy in the fairy tale books, ‘my how big your teeth are Grandma….’This costume idea (from Little Red Riding Hood) is awesome although you may end up saying ‘all the better to eat you’ all night, but that could be fun as it’s certainly an ice breaker!
Big Game Hunter
Biker
Bishop
Black Swan – a dramatic ballerina costume idea based on the movie of the same name, if you want to use this costume idea then be sure to check out YouTube for makeup tutorials as Natalie Portman’s make-up in the movie really pulled the look together.
Bloody Costume Section – There are lots of different ideas for this from the Bloody Bride, Bloody Doctor, Bloody Surgeon or more. You could even just wear an old outfit of your own with fake blood over it and call yourself a bloody car crash victim.
Blues Brothers
Bluto – if you’re stuck on an idea and you’re running out of time then grab a sheet and wear it like a toga, just like Bluto in the movie Animal House.
Bo Peep

Bollywood Actress Costume Men’s Bishop Costume Bonnie Parker Costume

Bob the Builder
Bollywood Star
Bonnie Parker – of Bonnie and Clyde fame; dress up in 1930s fashion and carry a handgun (a pretend one, it is a party you’re going to after all).
(A) Box – the easiest of all costumes, just pop yourself in a box!
Boxer
Boy George – a classic 80s costume idea, you can find a ready-made Boy George costume on my 80s Costumes Ideas for Men, alternatively, you just need dreadlocks, makeup and a long duster coat!
Brave
Braveheart
Bride – you can go as a classic bride, an undead bride, Bride of Chucky or Bride of Frankenstein
Britannia – I don’t think that there’s an actual Britannia costume so you could wear a Union Jack dress and call yourself Britannia or you could wear a long robe with a Roman-style helmet, trident and Union Jack shield as a cross between the British warrior queen, Boadicea and a goddess of war with a little nod to Britain with the Union Jack. If you can’t get a Union Jack shield then just use a plain shield, but have the Union Jack like a cape essentially a British superhero!
Britney Spears
Buccaneer – a buccaneer is essentially another name for a pirate so if you need more inspiration then check out my pirate costume page.
Buddha
Buddy Holly
Buddy the Elf
Buffalo Bill
Bugs Bunny
Bumblebee
Bunny
Bunny Girl – this is a very easy costume to pull off in fact my father managed to pull this off for a party when I was a teenager, I remember because I had to help him paint his nails red! Simply wear a leotard with bunny ears and a white cottontail on your bottom. Wear high heels and walk with a wiggle!
Burglar – as a last-minute costume this is a good one, dark clothes and a ski mask is all you’ll need.
Burlesque Babe
Butler
Butterfly
Buzz Lightyear

I hope you’ve found some great ideas here for costumes beginning with B, if you’re after costume ideas for different letters then you need to visit my A-Z of costumes page.
