Trio Halloween Costumes | Attractive Halloween Costumes for Groups of 3

This post is about trio Halloween costumes. 

Halloween is an unbelievably fun time for college students. You get to go out to Halloween parties with your new college friends, meet new people, and start experiencing college. 

For many college students, there’s a lot of stress that comes with choosing a Halloween outfit. You want the outfit to be super cute and trendy, easy to achieve, and budget friendly. Unfortunately, this can be quite the research feat. 

To help you along in your college halloween costume quest, I compiled a post of the best Halloween outfits that I could find – for groups of three. If you plan on heading out on the town with two of your besties, this post will help you with all of your Halloween costume planning! 

Here are 15 college trio Halloween costumes for you and your two besties.

TENNIS PLAYERS

@unknown

If you or your friends played tennis in high school, this is definitely the kind of glow up costume you need to put together. I love how cute the pieces are on their own, too, so they can be easily repurposed into non-costume outfits. If your trio is two boys and one girl, you can even put a Challengers twist on it.

Sexy Sleeveless Crop Tops

SNOWBOARDERS OR SKIERS

@unknown

I really like that this costume works in cold or hot climates! In hot climates, it’s ironic and funny, and in cold climates, it’s a perfect spin. Plus, if you live in a cold climate, odds are that you can easily copy this costume from stuff you already have in your closet. What a win! These are the perfect costumes for three friends!

TRIO HALLOWEEN COSTUMES: MUMMIES

@unknown

This costume idea puts a sexy spin on the classic wrapped in toilet paper look. The two piece outfit that I linked above is perfect for your base layer, and then the rest of the costume is as simple as wrapping yourself in gauze. Finish it off with some bronzer in place of dirt!

TRIO HALLOWEEN COSTUMES: COWGIRLS

@unknown

Dressing as a cowgirl is always a good experience, especially if you do it super ironically. One time I heard about a party where the theme was western, and you dressed up in western gear. I heard that this theme made the party hilarious, and I can guess that three cowgirls entering any party is going to bring that same level of energy.

With the new Wicked movie coming out this year, there’s no better time to dress as The Wicked Witch of the West, The Good Witch, and Dorothy for Halloween!
