29 Best Friend Halloween Costumes
So, you and your bestie decided to go all out for Halloween this year? Good choice.
IMO, Halloween is way more fun when you’re not rolling solo but matching outfits with your ride-or-die. After all, what screams “unbreakable bond” louder than showing up to the party dressed as peanut butter and jelly or two halves of an iconic duo? Exactly.
Let’s be real—picking a Halloween costume is stressful enough.
Add in the pressure of coordinating with your best friend, and suddenly you’re scrolling TikTok at 2 a.m. wondering if dressing as salt and pepper is “basic” or “ironically genius.”
Don’t worry—I’ve got you covered. Below are 29 best friend Halloween costume ideas that are equal parts funny, creative, and guaranteed to get you both attention (the good kind).
1. Peanut Butter & Jelly
Classic. Simple. Everyone loves it. You can DIY this with oversized shirts or buy a ready-made costume. Bonus points if one of you brings actual sandwiches for party snacks.
2. Mario & Luigi
Want nostalgia points? Go with this. Red and green overalls, mustaches, and maybe a plastic wrench to look extra convincing. Trust me, people will yell “It’s-a me!” at you all night.
3. Barbie & Ken
Thanks to the Barbie movie, this duo is hotter than ever. Whether you’re Rollerblade Barbie & Ken or just going full pink vs. full denim, it’s a crowd favorite.
4. Netflix & Chill
Okay, hear me out—it’s punny and hilarious. One of you wears a Netflix logo shirt, the other literally writes “chill” on an outfit.
If anyone asks what you are, just give them the look. 😉
5. Cher & Dionne (Clueless)
If you don’t dress as these 90s icons at least once, are you even best friends? Grab plaid skirts, knee-high socks, and maybe practice a “Ugh, as if!” before the party.
6. Salt & Pepper
Minimal effort, maximum payoff. One wears all white with a big “S,” the other wears all black with a “P.” Cheap, cute, and instantly recognizable.
7. Wednesday & Enid (Wednesday)
For besties with totally opposite vibes, this is perfect. One goes goth chic, the other pastel rainbow.
Honestly, this might be the most accurate friendship costume ever.
8. Cowgirl & Alien
Yeehaw meets Area 51. One of you rocks cowboy boots and fringe, the other goes metallic with some neon.
It’s weird, fun, and definitely a conversation starter.
9. Thing 1 & Thing 2 (Dr. Seuss)
Blue wigs + red outfits = chaos energy in costume form. If you and your bestie are known for trouble, this one’s basically your uniform.
10. Velma & Daphne (Scooby-Doo)
Orange sweater or purple dress? Glasses or headband? This classic duo works every time. Pro tip: bring Scooby snacks to share. Instant popularity.
11. Angel & Devil
Because every friendship has that one “bad influence” friend. 😉 Decide who’s who, grab some wings and a halo/horns, and you’re golden.
12. Powerpuff Girls (Pick Two)
Yes, there are three of them, but you can always just rock Blossom and Bubbles—or Buttercup and whoever matches your vibe best.
13. Shrek & Donkey
If you don’t mind looking goofy, this one kills. Shrek ears, green face paint, and a donkey onesie. Be prepared for people quoting the movie at you all night.
14. Taylor Swift & Travis Kelce
This one’s basically the 2025 couple costume. One of you rocks a sparkly Taylor outfit, the other goes full Chiefs jersey. Easy and instantly recognized.
15. Sun & Moon
One glowing gold, one shimmering silver. Paint your faces, wear celestial outfits, and be the yin to your friend’s yang.
16. M&Ms
Pick two colors, slap big “M” letters on your shirts, and boom—you’re candy. Bonus: carry a bag of actual M&Ms around and make instant friends.
17. Hogwarts Students
Whether you’re Gryffindor + Slytherin or Ravenclaw + Hufflepuff, matching robes are always a hit. Wands are optional but highly encouraged for dramatic flair.
18. Ghostbusters
Grab jumpsuits, slap a DIY “Ghostbusters” patch on, and carry toy proton packs. Who you gonna call? You two.
19. Mermaid & Pirate
Because let’s be real, one of you is the whimsical dreamer and the other is just here for chaos. Pair a sparkly tail with a rugged pirate outfit.
20. 80s Aerobics Duo
Neon leggings, sweatbands, oversized tees, and leg warmers. Perfect if you’re ready to dance all night without taking yourself too seriously.
21. Starbucks Barista & Latte
One of you wears a green apron, the other becomes a giant cup of coffee. People will ask for pumpkin spice refills.
22. Gomez & Morticia Addams
Elegant, spooky, and perfect if you want to lean a little romantic with your bestie’s costume (or, ya know, just freak people out with dramatic poses).
23. Buzz Lightyear & Woody
To infinity and beyond… with matching cowboy boots and space helmets. This one is instantly recognizable and great for Disney fans.
24. Opposite Day
This one’s hilarious. Dress exactly like your bestie but swap personalities for the night. The inside jokes alone will be worth it.
25. Britney Spears & Christina Aguilera
Iconic pop princess vibes. Think red leather jumpsuit vs. “Dirrty” outfit. Karaoke battle highly recommended.
26. Pac-Man & Ghost
One circles around chasing candy, the other hides behind furniture and runs away dramatically. Fun, easy, and surprisingly interactive.
27. Frappuccino & Donut
Because caffeine and sugar are a friendship. One of you becomes Starbucks’ finest creation, the other a sprinkle donut. Adorable.
28. Zombies
Grab some ripped clothes, splatter fake blood, and practice your best zombie walk. Cheap, easy, and you can go as gory or cute as you want.
29. TikTok Trends Duo
This one changes every year, but you can recreate a viral dance meme or dress like trending TikTok characters.
If people don’t get it? That’s on them for not being online enough. 😛
Tips for Pulling Off Best Friend Costumes
Alright, before you run off to Amazon or start hot-gluing fabric at midnight, let’s go over a few quick tips:
- Plan early. If you want the really good costumes, don’t wait until October 30th. (Been there. Ended up as a “last-minute vampire” with a torn hoodie. Not cute.)
- Coordinate vibes. If one of you wants scary and the other wants funny, it might clash. Agree on a theme first.
- DIY or buy? Some of these are super DIY-friendly (like Salt & Pepper), while others might need an actual purchase. Decide how much effort you’re down for.
- Comfort > everything. Trust me, that skin-tight vinyl bodysuit looks cool… until you’re two hours in and can’t sit down. Always test your costume for mobility.
- Props make it. Even a simple outfit goes next level with a prop—like Scooby snacks, fake swords, or oversized coffee cups.
Final Thoughts
Halloween isn’t just about candy (although, let’s be honest, candy is a huge perk). It’s about showing off your personality, being ridiculous for one night, and making memories you’ll laugh about for years. And nothing says “we’re in this together” like a best friend Halloween costume.
So, whether you go for classic duos like Mario and Luigi, funny punny ones like Netflix & Chill, or trend-based costumes like Taylor & Travis, the key is to have fun and own it.
Because at the end of the night, no one’s going to remember if your horns were a little crooked or your Shrek ears kept falling off. They’ll remember that you and your bestie showed up, matched, and absolutely owned the vibe.
Now spill—are you leaning more toward funny, spooky, or full-on glam this year? 😉
