40 Iconic Trio Halloween Costumes Because All Good Things Come in Threes
We've got ideas for friends and families that you can buy or easily DIY.
They say all good things come in threes, and we couldn’t agree more. And while dressing up in a killer costume on October 31 is great, nothing beats showing up to a party in a coordinating group getup. Not sure where to begin? While there are plenty of cool duo looks, three-person Halloween costumes are just iconic because in television, movies and music, three seems to be the luckiest number (the Harry Potter crew, Destiny's Child, the Sanderson Sisters — just to name a few).
Now, when it comes to executing a three-person fit, whether you're going with your friends or family, you have options. You could go for a variation of the same idea that will have everyone seeing triple (witches, cats, etc.), or you could straight up embody some friends from pop culture or throughout history. Maybe you’ll opt to create laughs when you compliment each other as a food-themed look (S’more or BLT anyone?). Or perhaps you’ll decide to go as a group from your favorite TV show or movie. Whatever your choice, the most important rule when creating any trio costume is to have fun.
Whether you’re pulling your inspiration from Pinterest, trying to buy or are determined to DIY your way to the winner's circle at this year’s Halloween costume contest, all the ideas we have listed below are sure to help you pull off your best costume yet.
Power Puff Girls
Few cartoon characters are as awesome as the Power Puff girls. They fight crime, they have a good time and they wear the cutest clothes. You can opt for a DIY route that would just include a dress in the right color.
OK, so they're not so little. These blow-up pig costumes will work for all three of you, and you're bound to get a positive reaction.
Avocado Toast
For a too-cute family Halloween costume is so easy to make, plus it works as a maternity outfit. If you have a fourth in your family, feel free to have them go as an orange juice.
Destiny's Child
There are so many incredible outfits you can pick from, but this is one of the easiest. Some silver dresses and microphones, and you're all set.
If you can't make your minds up about the ultimate Halloween costume for three, consider playing Rock, Paper, Scissors ... literally.
Sutton, Jane and Kat from The Bold Type
You can literally wear any cool outfit you want and pull-off this costume, making it the ultimate last-minute idea. Maybe just print out a fake Scarlet Magazine to really drive the point home.
Hungry, Hungry Hippos
Another great family look, even if you don't have a toddler! Just get some colorful outfits and styrofoam balls, and you're halfway there.

80s Icons
You don't have to go matchy-matchy for a great costume. Each of you just need to pick a singer from the 80s and dress up like them. Trust us, people will definitely know you're together.
You see them all the time, but have you ever thought of transforming yourself into an air dancer? Now, you can, and this three pack makes it even easier to get your friends involved.
Minions
We absolutely LOVE this costume because it's so cute and easy to pull off. As a bonus, everything you have to buy for the look can be reused later on.

Instagram Filters
To make this costume, pull up Instagram stories on your phone and select the filter of your choice (have everyone in your crew pick a different one). Then, point the phone at a blank surface, and take a screenshot. Send the screenshot file to a printing or office supplies store to have it blown up and printed on a thick board. Then, cut out a part in the middle for your face. Use makeup and accessories to recreate the filter's effects, whether it's heart sunglasses, face highlighter, or dog ears.
Everyone loves a good BLT. Recreate the delicious snack with this three person getup that's also very work appropriate.
Who you gonna call? Your family that's who. No ghosts will want to mess with you this Halloween when you're rocking these fun getups.
These M&M costumes are perfect for a night filled with candy! For the complete look, pair these shirts with a tutu and white gloves.
You and your besties are anything but average. Show everyone that by dressing up as the stars of the ever-iconic Dodgeball.
Salem Witch Sisters from Hocus Pocus
If the little ones want to dress up as the Salem sisters from the Halloween classic Hocus Pocus, this Etsy shop makes elaborate leotards that adorably replicate the real Salem outfits. Note that tutus aren't included in this purchase.
Who doesn’t love this perfect campfire snack?! Your trio can decide who will be the graham cracker, marshmallow and chocolate!
This fire costume will definitely get people talking. Dress up as a Fireball tank, bottle and shot glass for a night full of fun.
Salt, Tequila, Lime
If you're never one to shy away from a shot — and neither are your two besties — then go as the classic salt, tequila, lime combo.
If you're super into dental hygiene, this hilarious set is the way to go. No one will be able to take their eyes off of your pearly whites in this costume.
