Three’s a Charm: Creative Trio Halloween Costumes for You and the Girls

Ready to turn heads this Halloween? Whether you’re dressing up with your best friends, teaming up with your sisters, or planning the ultimate group costume, The Harris Sisters have rounded up our best trio Halloween ideas just for you. With these picture-perfect outfits, we've got an era for everybody. And these creative costumes will have you and your girls stealing the spotlight all spooky season long.



Circus / Life of a Showgirl 

The Harris Sisters were in our showgirl era way back in 2020 and with so many circus characters to choose from, it's an easy one for a group of three. You can find extra details about our costumes here: Circus Themed Family Photoshoot.



Disney Villains

Why should princesses get all the love? There are just as many Disney Villains to choose from, and in keeping with the spooky them of the season, they're the perfect choice for a group of three. For more details on our Maleficent, Ursula, and Cruella DeVil costumes, take a peek here Disney Villains Group Halloween Costume.



Flower Garden

It does not get more simple than this when it comes to costumes: a giant flower fascinator and a green outfit. BOOM! You and your sisters are a flower garden. These flower fascinators were hand-crafted and hand-painted by the super-talented Harris Sister Misty, but you can find similar flower hats and flower fascinators online.



River Sirens / Woodland Fairies

When we wore these costumes, we were inspired by the River Sirens from the movie Oh Brother, Where Art Thou? But you can use the same ethereal look to create a trio of Woodland Fairies (just add wings!) More information on the costumes here River Sirens Photoshoot.




Barbies

What's better than one great Barbie costume? Three! There are so many iconic Barbie looks that this is a fun choice for a group of friends. Since the Barbie movie was released in 2023, there are a variety of Barbie costumes to choose from. We're shown here as vintage Barbie Learns to Cook, Original Barbie, and Great Shape Barbie.



Sanderson Sisters

Nothing says Halloween more than the cult classic 1990s Halloween movie Hocus Pocus. When dressing up as everyone's favorite sisters, your hardest decision will be who is Winifred, who is Mary, and who is Sarah. Once you get that sorted, the Sanderson Sisters costumes are easy to recognize this time of year and will be perfect for a group of three friends,




Classic 1980s

You and your homegirls can like totally recreate these 1980s costumes. Just make sure to get all of your slang ready to get into character in time for Halloween (for sure, excellent, bodacious, radical). Take a peek here for all the details Takin' It Back to the Old School.


Clue Characters

Three or six friends can use this idea for the perfect group Halloween costume. Pick your favorite characters from this classic board game and go wild! Here we're dressed as Miss Scarlett, Mrs. Peacock, and Mrs. White, but check out photos of us as Colonel Mustard, Mr. Green, and Professor Plum and all the costume details here Clue Halloween Group Halloween Costume.














Pirates

Arrgh, mateys! Pirate costumes are a popular choice for group costumes, but I'll let you in on a secret: they're also usually pretty easy to throw together last-minute. Why? Staples in the costumes include many pieces you may already own: ruffled blouse, long jacket or coat (think velvet, brocade, or leather), multiple scarves and belts, hoop earrings, dark pants or skirt, and tall boots. Pro tip: Dollar stores often sell pirate eye patches near Halloween, and tri-corn hats are often sold at party stores. Raid your kids toys for "weaponry." Layer, layer, layer! 



Dorothy from The Wizard of Oz / Wicked

When deciding on your group Halloween costume, don't be afraid to think outside of the box. In 2021, rather than dressing as three separate characters from The Wizard of Oz, we chose to all do a different take on the Dorothy costume. Pop over to this post for more details on the individual costumes Dorothy from The Wizard of Oz: Group Halloween Costume.



Storybook Characters

If you're a little more traditional, then we've got the perfect trio costume for you and the girls. These storybook characters are easy to recognize, just Over the Rainbow and Through the Looking Glass, to Grandmother's House We Go! and you'll find Dorothy (again), Alice, and Red Riding Hood. 



Flappers / Roaring 20's

You and your sisters will be the bee's knees in this iconic look and it's so easy to recreate. Just pair your flapper dress with accessories like pearl necklaces, headbands, and gloves. Make sure to put on your best dancing shoes because you'll be doing the Charleston all night!


Regency / Brigerton / Victorian Era

Make sure to read all our tips on Shopping Your Local Theater Company Sales. You might be surprised what you could score for your group Regency Halloween costumes. Or check online for Brigerton costumes and Victorian costumes. And don't forget to accessorize with items like tiaras, fascinators, lace gloves, brooches, and pearls.





Mechanics

For mechanic group costume look, we snagged three matching speed suits and added customized name patches to make them seem "official." To complete the costumes, we added red accessories we already owned.



Who says three’s a crowd? This Halloween, three is officially a vibe! Squad goals take on a whole new meaning when Halloween rolls around. If you and your friends (or sisters!) are looking for the best group costumes to rock this spooky season, we hope this list will do the trick. 

Get ready to make your trio the star of the night and pin these ideas for later.
