The 39 Best Duo Halloween Costumes for 2024

Halloween is one of my all-time favorite days of the year. Not only do I love dressing up by myself, but I also love planning Halloween costumes for me and my best friend. When has something not been more fun when you do it with the person you're closest to? Luckily, a lot of 2024's top costumes are applicable if you're part of a duo.

This list of best friend Halloween costumes is chock-full of new ideas that will feel entirely relevant in 2024—plus a few Halloween classics for duos that are bound to please year in and year out. So whether you want to trick-or-treat as Lorelai and Rory Gilmore of Stars Hollow fame or as Carmy and Sydney from The Bear, I promise something on this list is for you. You can even sweat it out as Charli XCX and her bestie Troye Sivan (or Lorde). Chances are, you probably have a bunch of the pieces to make these costumes come to life already hanging in your closet. (A large chunk of them rely on jeans and white T-shirts to work.) Consider this a foolproof guide to duo costumes for 2024.

If you're not really the dressing-up type, Marie Claire also has guides to costumes you can make out of a little black dress that are perennially chic, not to mention easy to master last minute. Or, if you're the kind of person who lives for an of-the-moment costume, check out our definitive list of costumes inspired by movies and TV shows.

Charli XCX and Troye Sivan

Turn Brat Summer into Sweat Tour Fall by dressing up as Troye and Charli this Halloween. Their looks are so easy to master—all you need are white tanks, Brat green, mico-mini skirts, and track pants (and plenty of smokey eye makeup).

Charli XCX and Lorde

People say they're alike, they've got the same hair! Lorde and Charli XCX make the perfect costume for you and your friend who look alike—nothing to be "girl, so confused" about here.

Patrick Zweig and Art Donaldson from 'Challengers'

Grab your churros and your Nike Killshot 2 sneakers—we're going as Art and Patrick from Challengers this year. Bonus points if you carry a tennis racquet around all night.

Sabrina Carpenter and Jenna Ortega in the "Taste" Music Video

This is one of those costumes where you probably own everything you need: a little black dress, black heels, and a best friend with the opposite hair color. A toxic boyfriend is not included (or needed).

Galinda and Elphaba from 'Wicked'

Yes, you're reading that correctly—Glinda is actually Galinda in theWicked movie. It may be coming out after Halloween, but I think a ton of bestie duos are going to go as these two this year.

Deadpool and Wolverine from 'Deadpool & Wolverine'

Gigi Hadid and Blake Lively already twinned in red and yellow outfits at the Deadpool & Wolverine premiere, but don't let that stop you and your best friend from doing the same thing this Halloween.

Lydia and Beetlejuice from 'Beetlejuice Beetlejuice'

New movie, same vibe—Lydia and Beetlejuice are back in Beetlejuice Beetlejuice this year, so master their look with a gothic costume. Winona Ryder's iconic smoky eyes and spiky hair teamed with Micheal Keaton's rimmed makeup and striped matching suit are easy to copy.

Patrick Mahomes and Travis Kelce

Go as everyone's favorite football besties this year. Now that Taylor Swift is a regular attendee, you have yet another excuse to add a few more Chiefs jerseys to your fall wardrobe.

Carlos Sainz and Charles Leclerc

Their time together may be coming to a close, but Carlos Sainz and Charles Leclerc still deserve a spot in your costume lineup. Red jumpsuits and matching red sneakers complete the look—I suggest the Puma Speedcat.

Carmy and Sydney from 'The Bear'

You probably already have a white T-shirt in your collection, so pull it out for this super easy costume inspired by The Bear. One of Sydney's trademark bandanas and matching blue apron complete the look. Let it rip!

Molly Gunn and Ray Schleine from 'Uptown Girls'

Seeing Dakota Fanning on the 2024 Emmy's red carpet got me thinking about one of her most iconic roles—Lorraine"Ray" Schleine in Uptown Girls. Her look is defined by her sharp bob haircut, sleek black sunglasses, and preppy private school uniform. Molly Gunn's look, however, is more inspired by her playful dresses (many of which hail from It-brand Blumarine) and her wavy hair.

Hannah Montana and Miley Cyrus

Miley Cyrus and Hannah Montana are one of the most iconic duos of the early aughts, and going as them this Halloween is, wait for it, the "Best of Both Worlds."

Ken and Barbie from 'Barbie' 

The Barbie movie is coming, people! Channel your favorite '80s toy icons by copying Margot Robbie and Ryan Gosling's outfits from these on-set photos that debuted last year.

The Sharma Sisters from 'Bridgerton'

Bridgerton's sister duo also makes for a killer costume for Halloween 2024. Kate Sharma is known for her bold colors while her sister, Edwina, wears lighter pastels.

Eleven and Max from 'Stranger Things' 

Max Mayfield and Eleven became the best of friends in season three of Stranger Things, so they channel their '80s style energy by copying their looks this Halloween. Max is known for her high-top Vans sneakers and laid-back style, whereas Eleven is almost exclusively in bright colors that season.

Steve and Robin from 'Stranger Things'

You have a few options when it comes to Steve and Robin costumes for Halloween this year. There are, of course, the iconic Scoops Ahoy uniforms, plus their later looks at the video store. Either way, this duo is tough to beat.

Drea and Eleanor from 'Do Revenge' 

Netflix's movie Do Revenge is ripe with costume inspiration for besties in 2024. Drea and Eleanor have many, many outfits to copy, but their full-on glam look from the end of the movie is my personal favorite.

Cher and Dionne from 'Clueless'

Cher and Dionne's costumes are instantly iconic and there are tons of ways to Clueless-ify your looks. If you're going as Cher, either pick out a plaid mini skirt in yellow, or just wear a yellow skirt suit. For Dionne, feel free to wear black, white, and red. A funky hat is a must!

Peanut Butter and Jelly

There's nothing cuter (or easier) than going as peanut butter and jelly with your bestie this year. There are two ways to make this work: pair black leggings with either a berry or a brown t-shirt (bonus points if you DIY your costume), or shop pre-made costumes.

Tia & Tamera from 'Sister, Sister'

This costume is all about rocking double denim and '90s-inspired prints and colors. The must-buys include a pair of overalls, a denim bucket hat, and a chunky sweater.

Cassie and Maddy from 'Euphoria' 

Cassie and Maddy might not be besties at this point on Euphoria, but that doesn't mean you can't throw it back to season one when they were!

Rachel and Monica from 'Friends'

You know the vibes here: If you're going as Rachel, wear a vintage Knicks basketball sweatshirt or, if you're really going for it, a bridal gown. For Monica, wear a retro slip dress, a cropped cardigan with jeans, or a white button-down shirt tucked into some dad jeans.

Megan Rapinoe and Alex Morgan 

If you're going as everyone's favorite soccer besties, there are a few easy ways to nail the costume. Pink hair dye is a must, obviously, as are jerseys for both players. Feel free to make them yourself or buy an official set to rep team USA all year long.

Pink Ladies from 'Grease'

It's time to rep your favorite '50s-era girl group. Think: tightly curled hair, pink bandanas, black cat-eye sunglasses, and the iconic pink bomber jackets. If you don't want to buy a lookalike from the movie, wear pink denim jackets instead.

Lizzie and Isabella from 'The Lizzie McGuire Movie' 

No singing skills are required for this costume. One of you should dress in a lavender mini dress, while the other wears one in lime green. Easy!

Serena and Blair from 'Gossip Girl'

Serena and Blair are one of TV's most memorable duos for a reason. Headbands and patterned tights are key to nailing Blair's look, while Serena normally takes a boho approach with beachy waves and oversize blazers and boyfriend-inspired button-downs.

Thelma and Louise

Maybe one of the easiest costumes on this list to master, going as Thelma and Louise just requires you to wear a white or black tank and high-rise jeans. Don't forget the sunglasses!

Romy and Michele from 'Romy and Michele's High School Reunion'

To get the full Romy and Michelle effect, you need to pick up pink and blue fur-lined mini dresses. However, regular old mini dresses (ones without fur) will work just fine, too.

Minions 

Everyone loves to hate on the Minions, but that doesn't mean they don't make a super easy last-minute costume. Yellow tees and turtlenecks layered under blue overalls will make you and your friend (or your entire friend group) look totally on-theme.

Christina Yang and Meredith Grey from 'Grey's Anatomy' 

Another easy costume in the books! Blue scrubs and white doctor's lab coats are all you need. Simple!

Mary-Kate and Ashley Olsen 

For friends who dream of owning outfits from The Row. Head-to-toe neutrals are required, as are oversized sunglasses and barely-there makeup.

'Wayne's World'

A black trucker hat, oversized square black glasses, and coordinating T-shirts are the key to mastering this cult-classic costume. Don't forget to keep "Bohemian Rhapsody" on repeat all night long.

Lucy and Ethel From 'I Love Lucy'

Matching polka-dot dresses, sheer pantyhose, and low-heeled pumps are perfect for this best friend costume. Bonus points for pincurled hair and red lipstick.

Ghostbusters

This is another time when buying a pre-made Ghostbusters costume might make more sense than making one yourself. If you're feeling especially crafty, a dark green boiler suit will do the trick.

Raven and Chelsea from 'That's So Raven' 

Oh snap! I love this duo costume because it lets your personal styles shine. Bright patterns, flared jeans, and frosty eyeshadows are all must-buys.

Max and Caroline from '2 Broke Girls' 

Pull on yellow mini dresses and red aprons to master this duo's look from 2 Broke Girls. This is also perfect if one of you is a redhead and the other is a brunette.

Daphne & Velma from 'Scooby Doo' 

Scooby Doo!-inspired costumes never go out of style. Daphne's purple-and-green ensemble is a go-to for a reason. Just make sure you have white knee-high boots. For Velma, all-orange is the way to go, complete with black square glasses. Bonus points for a brown bob wig!

Lewis Hamilton and Max Verstappen

F1 fans, this is for you. Max Verstappen and Lewis Hamilton duked it out for the 2021 championship, and three years later, it's still a great costume.

Lorelai and Rory Gilmore

Rory and Lorelai Gilmore's outfits are the pinnacle of fall attire. Whether you're rocking Lorelai's first-day-at-Chilton-look (read: Daisy Dukes and cowboy boots) or Rory's classic school uniform, there are plenty of great style moments to choose from.

The Contestants from 'Squid Game'

Green light! DIY a Squid Game Halloween costume with your favorite dark green sweatsuits. Don't forget to paint some faux blood on your face, and pick up a pair of new white slip-on-sneakers.
