Well, folks, 'tis the spooky season and that means it's time to give yourself a check: Have you planned your Halloween costume? No? Welp, look at the date because it's fast approaching and you're running out of time. But before you freak, take a beat because we've got you and your BFF covered with some of the greatest best friend Halloween costumes out there. Honestly, let's be real, nothing's better than dressing up with a friend. (Have more than one BFF? We've gotchu covered with our group Halloween costume ideas.)
From TV show and movie character duos to pop culture costumes, we've rounded up a whole bunch of best friend Halloween costume ideas for you and your bestie to get inspired by. Trust, we've covered a wide range of ideas with looks inspired by everything from popular series Bridgerton and Euphoria to '90s classics like Clueless and Napolean Dynamite. Now grab your bestie and get to shopping because Halloween is right around the corner.
Maddy and Cassie
Yep, this matching sweatsuit moment from the second season of Euphoria is the ideal bestie costume.
Black and White Swans
Yes, a Black Swan costume is always a good idea, but taking it up a notch by having you and your bestie go as both the black and white swan from the creepy thriller? Even better.
Brooke and Peyton
If you're a die-hard OTH fan, bring it back to the aughts with a classic Brooke and Peyton get-up. My rec? Two Ravens cheerleader outfits so everyone knows exactly who you are.
Daisy Jones and Karen Sirko
Queue up the rock ‘n roll and break out your best bell-bottom jeans for this fun '70s-inspired costume. (Don’t forget the microphones!)
The Pink Ladies
One of the easiest (and forever classic!) Halloween costumes for a trio is The Pink Ladies from Grease. IMO, there's not a more iconic gal group.
Wednesday and Enid Sinclair
This is a classic costume idea that'll never get old, but Jenna Ortega gave us a modernized Wednesday Addams, which is super fun to channel alongside polar opposite Enid Sinclair.
The Sanderson Sisters
Three BFFs? No prob, dress up as the Sanderson sisters, but add a lil *spice*.
Ilana and Abbi
Quite possibly one of the most hilarious duos to grace our televisions as of late, Illana and Abbi would win Halloween.
Bonnie, Elena, and Caroline
Two vampires and a witch? I think this Vampire Diaries trio screams Halloween if you're askin' me.
Taylor Swift and Phoebe Bridgers
Pay homage to Taylor Swift’s Eras Tour—or, in other words, the most iconic music tour to date, IMO—by channeling Swift and her tour BFF Phoebe Bridgers.
Mr. and Mrs. Smith
Last-minute per usual (hi, it me)? Mr. and Mrs. Smith is a costume that never fails.
Stranger Things
Season 4 villain Vecna makes a pretty good Halloween costume. To make it even better? Grab your BFF to dress up as Max and then take this iconic pic like Nina Dobrev and Shaun White.
Rory and Lorelai Gilmore
Sure, they may be a mother-and-daughter duo, but if you've seen even one episode of Gilmore Girls, you know that they're also BFFs.
Kim Kardashian and Paris Hilton
The early aughts just hit different. Coordinate with each other in these silver and gold chainmail dresses to channel Paris and Kim.
Mermaid Man and Barnacle Boy
Spongebob Squarepants-inspired costumes are always a win in our book.
The Grady Twins
Give everyone the creeps by dressing up in blue dresses and black Mary Janes worn by the spooky twins in The Shining.
Thelma and Louise
A movie about best friends makes the perfect costume for best friends, obviously. The fact that you probably already own all the pieces you need for your looks (minus the convertible) makes it even better.
Napoleon and Pedro
Remember when Napoleon Dynamite was the funniest movie in the world? About two decades later, it still makes for the funniest costume in the world.
Cher and Dionne
You'll def be rollin’ with the homies if you dress up as everyone's fave fashionable besties from Clueless.
Russell and Carl
Walk into the Halloween party in these Up ensembles, and you and your BFF will immediately win the best costume award, promise.
