I love fancy dress parties with themes where you have the chance to think outside of the box and one of the coolest theme ideas is costumes beginning with the party. Simply pick a random letter and say that it’s your theme – if it’s a birthday party you can just use the birthday person’s initial or else you can just pick your favorite letter. I think the most popular letter that I’ve come across is P, I’ve been to lots and lots of P parties whereas I haven’t been to a single A or L party!

To help you out I’ve come up with some fancy dress ideas that start with each letter of the alphabet, from apple to zebra or A-Z, so have fun choosing!
