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.

TRIO HALLOWEEN COSTUMES: TENNIS PLAYERS

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. 

TRIO HALLOWEEN COSTUMES: SNOWBOARDERS OR SKIERS 

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!

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: SUN, MOON, AND DEVIL

This is a cheap, easy costume that you can throw together extremely last minute. This costume is also perfect for warm climates where an outfit like this won’t leave you with hypothermia! If you live in a southern state, this is one of the best trio Halloween costumes. 

TRIO HALLOWEEN COSTUMES: WHITE CLAWS 

Bring your own drinks, and dress like them, too! White claws are such a popular college student drink, and dressing as one with your besties is a great Instagram opportunity.

If you’re looking for a costume that’s as easy as throwing on a swimsuit, this costume is literally that. Add some fake blood and you have both a conversation started and a photo opportunity. This is one of my favorite 3 person Halloween costumes. 

TRIO HALLOWEEN COSTUMES: COWGIRLS

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. 

TRIO HALLOWEEN COSTUMES: CLUELESS

I really love how a costume like this people are able to immediately recognize because it’s such a classic. Learn some lines from the movie and you’re set for a fun night! 

TRIO HALLOWEEN COSTUMES: GHOSTBUSTERS

Take ghostbusters to a new, sexy level with this super easy costume. I love that you’re able to buy this costume as one piece, making your Halloween shopping and preparing that much easier. Add your last names to the costumes, and you’re looking at some great three person Halloween costumes ideas. 

TRIO HALLOWEEN COSTUMES: THE FAIRLY ODD PARENTS

The Fairly OddParents costume got really popular when Kylie Jenner dressed up as this costume with her friends for Halloween. Channel your inner Kylie Jenner and rock the new take on this childhood classic. 

TRIO HALLOWEEN COSTUMES: MERMAIDS

I really love how creative you can get with a costume as simple as a mermaid. In this picture, the people wearing this costume dressed up their pieces with tons of shells and sequins, and they matched their costumes with their makeup. This is a great option to get creative! 

TRIO HALLOWEEN COSTUMES: TWO ANGELS AND A DEVIL

This costume is a sorority girl classic. I love how simple they are to put together, and they can be used at other events, too. This is a perfect example of group costumes for 3! 

TRIO HALLOWEEN COSTUMES: MEAN GIRLS

Just like dressing up as characters from “Clueless,” this costume is based off a movie classic. You will be immediately recognized by other party-goers, and you are setting yourself and your besties up for a fantastic photo opportunity. 

TRIO HALLOWEEN COSTUMES: HIPPIES

Dressing as a hippie is probably one of my favorite Halloween costumes. I’m not really sure why the fashion trends of this era went out, because they are so cute today. When you dress up as a hippie, you’re setting yourself up for adding some super gorgeous elements to your closet, too. 

TRIO HALLOWEEN COSTUMES: DISCO DANCERS

If you have some amazing dance moves, it’s a great idea to pair them with this fashion-forward costume. You’ll be super eye-catching on the dance floor, and ready to get the party started. Hit the dance floor with these perfect trio Halloween costumes.
