Art, Tashi, and Patrick from Challengers
I don't recommend getting yourself into an incredibly messy love triangle, but I do recommend this v topical costume idea.
Sonny Angels
These three-inch figurines that blew up the internet bring smiles, happiness, and company—but they also make an iconic three-person (or four, or five, etc.) Halloween costume.
Simone Biles, Rebeca Andrade, and Jordan Chiles
Want to recreate this viral moment from the 2024 Paris Olympics? Now is your chance!
Dylan, Natalie, and Alex from Charlie's Angels

I'm just gonna say it: Lucy, Drew, and Cameron are the most iconic Angels, IMO.
Dallas Cowboy Cheerleaders
Who wouldn't want to dress up like a trio of America's Sweethearts?
Moo Deng, Moo Wan, and Moo Tun
Real ones know that Moo Deng has not one, but two siblings. Channel the viral, adorably funny, and cute pygmy hippos this Halloween.
Rachel, Monica, and Phoebe from Friends
If you can't pick one character from Friends, grab your BFFs and pick three! Plus, it gives you an excuse to wear all of your nineties clothes.
Mary, Winifred, and Sarah Sanderson from Hocus Pocus
Arguably one of the most well-known Halloween movies of alll time, dress up as the Winifred, Sarah, and Mary from Hocus Pocus with wigs, cloaks, mesh gloves, and overdone makeup.
Sutton, Jane, and Kat from The Bold Type

We may be just a lil biased, but we think besties who work in magazines are some of the greatest besties of all.
Gretchen, Regina, and Karen from Mean Girls
Put on your best pink 'fits and grab your Burn Book to look so fetch this Halloween.
Mabel, Charles, and Oliver from Only Murders in the Building
The trio from OMITB all have distinct senses of style that would be so fun to turn into a Halloween costume (but IMO, Selena's wedding dress moment is especially iconic).
Austin Powers, Foxxy Cleopatra, and a Fembot in Austin Powers in Goldmember
I can't tell which Austin Powers costume I like best?!? Whichever character you get, you'll be totally ~groovin'~.
The Chanels from Scream Queens

Just saying: Season One of Scream Queens is TV gold, and dressing up as the Chanels will never get old.
Kate, Javi, and Tyler from Twisters
Here's hoping Halloween is a windy night if you and your crew decide to go with this one!
Alana, Danielle, and Este Haim
No, you can't become the fourth Haim sister—but with a black bra top and slouchy pants, you and your two besties can look just like the singing sisters.
Donna and the Dynamos from Mamma Mia! Here We Go Again
10/10 would be friends with Donna, Tanya, and Rosie.
Sam, Clover, and Alex from Totally Spies!
Anyone who grew up watching Cartoon Network will ~totally~ appreciate this costume.
Blossom, Bubbles, and Buttercup from The Powerpuff Girls
Speaking of Cartoon Network! The Powerpuff Girls are a trio that can't be beat (and if you feel like the classic dress-and-Mary-Janes combo is overdone, you can always take on this fun Powerpuff Cowgirls lewk).
Salt, Pepa, and DJ Spinderella
Salt-N-Pepa's here, and we're in effect!
Swifties
Head's up: Halloween gives you the perfect excuse to wear your Eras Tour outfit again. Don't forget your friendship bracelets!!
