Halloween rolls around, and suddenly your “I have nothing to wear” panic triples. Sound familiar? Same. But here’s the good news: TikTok has basically turned into the world’s best costume mood board. If you’re searching for trendy duo Halloween costumes for women, TikTok has you covered with endless inspo. I’ve pulled together 14 of the most creative, fun, and yes—scroll-stopping—duo looks you and your bestie can totally rock this year.
Whether you’re aiming for cute, spooky, or “people will not shut up about this costume,” I’ve got you. And because I’ve lived the last-minute panic of piecing together a look from my closet at 4 p.m. on Halloween night (not recommended, BTW), I’m making sure these suggestions are both doable and attention-grabbing. Ready? Let’s get into it.
1. Barbie & Ken (The TikTok Edition)
If you haven’t seen Barbiecore explode all over TikTok, I’m honestly impressed—what rock are you living under? This year, Barbie & Ken isn’t just a costume, it’s practically a lifestyle.
- Barbie: Think hot pink mini dress, heels, and that confident smile.
- Ken: Pastel shorts, an open shirt, and yes—bring the rollerblades if you dare.4

This one’s perfect because it’s instantly recognizable, and you can add your own twist. Ever seen TikTokers do “Goth Barbie & Ken”? Yeah, it slaps.
2. Wednesday Addams & Enid Sinclair
If you and your bestie are basically opposites, this duo screams you. Wednesday is the moody, all-black queen, while Enid is the rainbow-sparkle-energy friend.
Why it works: Contrast. One of you gets to brood, the other gets to sparkle. Together? Chef’s kiss.
Plus, TikTok went wild with Wednesday dances—so yes, you must break into the choreography when the DJ plays “Goo Goo Muck.”
3. Angel & Devil (The TikTok Glow-Up Version)
Sure, Angel & Devil costumes are classic, but TikTok gave them a facelift. Instead of the cheap wings and plastic pitchforks, people are leveling up with rhinestone halos, feather wings, and sleek corsets.

Want to stand out? Do a role-reversal. Sweet angel in red, mischievous devil in white. Trust me, people love the twist.
4. Maddy & Cassie from Euphoria
Remember when TikTokers recreated Euphoria makeup looks every week? Yeah, that obsession never really ended.
- Maddy: Bold cat-eye, sleek outfits, maybe a rhinestone bodysuit.
- Cassie: Softer glam, pastels, maybe a tear-stained mascara look (bonus points for accuracy 😂).
This duo costume is perfect if you love makeup and drama. And let’s be real, who doesn’t?
5. Velma & Daphne (The TikTok “Glow-Up” Version)
Velma and Daphne went viral last year after creators turned the wholesome Scooby-Doo gang into fashion icons. Forget baggy sweaters—think cropped versions, thigh-high boots, and statement glasses.
It’s nostalgic and trendy, and IMO, that combo never misses.
6. TikTok Food Pairings (PB&J, Milk & Cookies, etc.)
TikTok LOVES food costumes. I once saw two girls dressed as Hot Cheetos & Ranch dip—and honestly, it was brilliant.
Some solid ideas:
- Peanut Butter & Jelly
- Milk & Cookies
- Fries & Ketchup

Why it works: Everyone instantly gets it, and you can DIY with t-shirts or go all-out with plush costumes.
7. Bratz Dolls
TikTok has revived the Y2K look, and Bratz-inspired fits are at the top of the list. Think bold makeup, chunky shoes, miniskirts, and sassy poses.
Pro tip: Carry a doll-sized purse or a flip phone for the full vibe. Bonus points if you and your friend strut into the party like you’re walking a runway.
8. Britney Spears & Christina Aguilera
Want a duo costume that screams early 2000s icon energy? TikTok fashion creators love recreating these two legends.
- Britney: “…Baby One More Time” schoolgirl fit or red catsuit.
- Christina: Low-rise jeans, crop top, choker necklace.
It’s campy, nostalgic, and people will sing your entrance theme.
9. Maddie & Liv from Disney’s Liv and Maddie
TikTok is obsessed with Disney nostalgia. Dressing as Liv and Maddie is hilariously easy—one twin in glam pink fits, the other in sporty basketball gear.
Even if no one immediately gets the reference, they’ll appreciate the twin-energy aesthetic. And you? You’ll feel comfy while still looking fun.
10. Winx Club Fairies
Fairycore meets nostalgia = Winx Club. TikTok creators are giving Winx transformations new life with sparkly wings, holographic skirts, and glittery eye makeup.
This duo costume lets you be bold with color. Pick your favorite fairies and lean into it. (If you’re Bloom, prepare for someone to yell, “Dragon Flame!” at you. Just accept it.)
11. Cher & Dionne from Clueless
TikTok has turned Clueless plaid into a forever trend. Cher’s yellow plaid, Dionne’s black-and-white set—both are instantly iconic.
Plus, you can order affordable replicas online, so no stressing about sewing plaid skirts last-minute. (Been there, hated it.)
12. TikTok Filter Costumes
This one’s… clever. Dress as your favorite TikTok filters. One of you could be the Bold Glamour filter (glitter dress, rhinestones, exaggerated contour), while the other rocks the Shapeshifting filter (wear a morph suit with celeb printouts).
It’s meta, it’s funny, and TikTok-obsessed people will scream when they get it.
13. Mermaid & Pirate (The TikTok Aesthetic Version)
Mermaids are having a major TikTok moment thanks to The Little Mermaid trend and all those ocean-core edits. Pair it with a pirate and boom—iconic duo.

Want to spice it up? Make the pirate also glamorous with metallic accessories and smoky makeup. TikTok thrives on aesthetic mashups.
14. Corpse Bride & Victoria (Tim Burton Aesthetic)
Halloween meets romance. TikTok loves the gothic romance aesthetic, and Corpse Bride & Victoria is the perfect nod to it.
- Corpse Bride: Blue wig, flower crown, torn dress, pale makeup.
- Victoria: Vintage white gown, soft curls, subtle makeup.

This costume isn’t just beautiful—it’s dramatic. And IMO, the best Halloween costumes always carry a little drama.
Tips to Nail Your TikTok Duo Costume
Okay, so you picked a costume idea. But how do you make it TikTok-worthy (aka, extra)? Easy:
- Props are your BFF. Rollerblades, milk cartons, flip phones—tiny details = big impact.
- Commit to the bit. Don’t just wear the costume; embody the character. (Yes, practice the Wednesday dance in the mirror.)
- Make it trend-friendly. Add a TikTok audio to your entrance or film a quick clip before the party. Guaranteed likes.
And remember, TikTok costumes aren’t about perfection. They’re about fun, creativity, and a little bit of chaos.
