18 Group of 3 Halloween Costume Ideas

We love a group costume on Halloween. It opens up the door to a whole world of opportunities; you can go as a band or the cast of trending TV show like "The Summer I Turned Pretty"! Group costumes that would be hard to understand if you donned them solo make sense when you have a little more context, in the form of a couple of buddies. And group of three Halloween costumes are especially fun. It's not so many people that they're hard to wrangle, but enough that you can have as fun getting ready as you will on the big night itself.

Between you and your two friends, you probably already have some fantastic ideas. But if you're having trouble settling on one, we rounded up 18 ideas for group costumes for three to inspire you. These three-people halloween costumes range from store-bought to DIY-able, and they're pulled from pop culture, food culture, and more. You and your crew are sure to find a three-people Halloween costume that everyone loves, and that inspire a lot of laughs at your Halloween get-together.

If we have one pro tip for anyone who's considering group costume ideas for three people, though, it's this: share the Halloween costume, but don't share the Halloween candy.
