28 Duo Halloween Costumes
Halloween is basically the Super Bowl of creativity.
And let’s be real—nothing turns heads faster than a killer duo costume.
Whether you’re teaming up with your partner, your bestie, or even your sibling, a well-executed two-person costume can make you the life of the party (and rack up a ton of Instagram likes).
But here’s the kicker: picking the right costume is tough.
Do you go funny? Scary? Pop-culture inspired? Or do you just glue on some cat ears and call it a night? (Please don’t do the last one.)
That’s where I come in—I’ve rounded up 28 duo Halloween costumes that hit every vibe from hilarious to downright iconic.
1. Bonnie and Clyde
Because nothing says ride or die like America’s most infamous criminal couple.
You’ll just need a beret, trench coat, toy gun, and maybe a getaway car (kidding… kinda).
2. Mario and Luigi
The ultimate brotherly duo, even if you’re not related.
Overalls, fake mustaches, and red/green hats will make you instantly recognizable.
Bonus points if one of you insists on saying, “It’s-a me, Mario!” all night.
3. Barbie and Ken
Barbie-core is still having its moment.
Grab a pink dress, blonde wig, and let Ken rock some swim shorts or rollerblades. Instant crowd-pleaser.
4. Peanut Butter and Jelly
One of the easiest DIY costumes. You can buy ready-made PB&J outfits or just cut sandwich boards from cardboard.
Cheap, comfy, and universally loved.
5. Gomez and Morticia Addams
Elegant, spooky, and totally timeless.
Morticia’s long black dress and Gomez’s pinstripe suit scream gothic glam. Perfect for couples who want to stay in character all night.
6. Harry Potter and Hermione
You know someone’s going to show up in a Hogwarts robe, so why not beat them to it?
Grab scarves, wands, and robes—easy peasy. (FYI, carrying a butterbeer helps sell the look.)
7. Salt and Pepper Shakers
Simple but genius. One wears all white with a big “S,” the other wears all black with a “P.” Together, you’re a spice rack on legs.
8. Shrek and Donkey
Want laughs? Go full Shrek and Donkey.
Face paint, fake ears, and a donkey onesie = unstoppable. Be ready for everyone to yell, “In the mornin’, I’m makin’ waffles!”
9. Jack and Sally (The Nightmare Before Christmas)
Perfect if you lean toward spooky-romantic.
Sally’s patchwork dress and Jack’s striped suit will make you look like you just crawled out of Halloween Town.
10. Thing 1 and Thing 2
Dr. Seuss classics. Bright red jumpsuits and those ridiculous blue wigs make for a bold, colorful choice.
Best for high-energy duos who love chaos.
11. Cowboy and Cowgirl
Yeehaw! Easy to pull together with boots, hats, plaid shirts, and some sass. You’ll definitely get someone yelling, “Howdy, partner!” at least once.
12. Fred and Wilma Flintstone
Go prehistoric with this throwback. Animal-print outfits and big chunky “stone” jewelry make this instantly recognizable.
13. Scooby-Doo and Shaggy
Talk about best friend goals.
Grab a Scooby onesie and some green pants with a baggy shirt.
Don’t forget to carry snacks—Shaggy never goes anywhere without food.
14. Netflix and Chill
Cheeky, modern, and always gets a laugh.
One of you wears a Netflix shirt, the other wears a Chill shirt (with some ice packs taped on, if you want extra effort).
15. Ghostbusters Duo
Strap on some jumpsuits and proton packs (DIY from cardboard works too). Bonus points if you find a friend to be Slimer.
16. Angel and Devil
Classic duo. One of you rocks all white with a halo, the other wears all red with horns.
Works for couples or friends who want that good vs. evil energy.
17. SpongeBob and Patrick
Bright, goofy, and guaranteed to make everyone smile.
SpongeBob’s square pants and Patrick’s shorts are super easy to DIY.
18. Joker and Harley Quinn
If you like a little chaos (and neon hair dye), this one’s for you. Joker’s purple suit + Harley’s pigtails and bat = iconic.
19. Chip and Dale
Yes, the chipmunks. Grab brown outfits, tails, and little ears. Super cute and nostalgic.
20. Power Rangers (Red and Pink, or Any Pair)
Pick your favorite colors and go full Power Ranger. Spandex optional (but highly encouraged).
21. Edward Scissorhands and Kim
For fans of Tim Burton, this duo costume nails the dark and dreamy vibe. Scissor gloves + a flowy white dress = instant recognition.
22. Cat and Dog
Keep it simple. One of you throws on cat ears, the other wears a dog collar. Bonus if you commit to the bit with meows and barks all night.
23. Men in Black
Suits, sunglasses, and fake alien-zapping gadgets. Sleek, simple, and works well last-minute.
24. Pac-Man and Ghost
DIY with cardboard cutouts or grab a ready-made set.
One goes yellow, the other picks a ghost color. Extra cool if Pac-Man chases the ghost around the party.
25. Thelma and Louise
Ultimate girl power costume. Jeans, sunglasses, and a carefree attitude. Bonus points if you quote lines from the movie.
26. Woody and Buzz Lightyear
Toy Story legends. Woody’s cowboy hat and Buzz’s space suit make for a dynamic pairing. To infinity and the dance floor!
27. Wednesday and Enid (Wednesday Netflix Series)
Perfect for friends with opposite vibes. Wednesday wears all black, Enid goes pastel rainbow. The contrast makes this duo pop.
28. Frankenstein and Bride of Frankenstein
Old-school horror never goes out of style. Green face paint, stitches, bolts, and her iconic tall white-streaked hair complete the look.
Tips for Nailing Duo Halloween Costumes
Costumes aren’t just about what you wear—it’s about how you own it. Here are a few pro tips to make sure your duo costume hits hard:
- Commit to the character. Don’t just wear the costume—act the part. Shaggy without snacks? Weak.
- DIY when possible. Some of the funniest costumes come from cardboard, paint, and hot glue.
- Match your energy. If your partner is going full glam, maybe don’t show up in sweatpants and cat ears.
- Comfort matters. You’ll be moving, dancing, maybe sweating. Don’t pick something you’ll regret in 10 minutes.
- Add props. Even simple accessories make the costume way more convincing.
Why Duo Costumes Work So Well
Let’s be honest: Halloween can feel like a mini competition. Everyone wants the most clever, unique, or Instagram-worthy look. A duo costume doubles your creativity, gives you instant recognition, and usually comes with built-in humor or nostalgia.
Plus, let’s not ignore the obvious—it’s just way more fun to share the spotlight. Ever noticed how much easier it is to approach people when you’ve got a costume buddy? Exactly.
