Halloween with your bestie hits differently. Whether you’re plotting world domination together or just want the cutest Insta pics, finding the perfect costume combo can feel like a full-time job. I’ve been there—scrolling Pinterest at 2 a.m., panicking because Spirit Halloween is sold out of literally everything. Been there, done that, cried into my pumpkin spice latte.
So, to save you from that last-minute chaos (you’re welcome), I’ve rounded up 11 trendy Halloween costume ideas for female best friends. These aren’t your grandma’s “witch and cat” pairings (though hey, classics are classics). Instead, think modern, stylish, and just a little bit cheeky—costumes that make people go, “Omg, why didn’t we think of that?”
Ready? Let’s talk bestie goals.
1. Barbie & Ken (Or… Barbie & Barbie)
Honestly, 2023 gave us the Barbie-core era, and I don’t see it dying anytime soon. Barbie isn’t just a doll; she’s a lifestyle.
- One of you rocks classic pink Barbie vibes (think hot pink mini dress, chunky heels, oversized sunnies).
- The other? Either go full Ken mode (denim vest, rollerblades, bleached wig) or join the Barbie multiverse (cowgirl Barbie, weird Barbie, astronaut Barbie—you pick).

Why it slaps: It’s trendy, instantly recognizable, and you’ll get bonus points if you blast “I’m Just Ken” while walking into the party.
2. Wednesday & Enid (From Wednesday)
Let’s be honest—every friend duo has a Wednesday and an Enid. One’s brooding, sarcastic, and dressed in eternal black. The other’s sunshine in human form with a rainbow closet.
- Wednesday: Black dress, braids, resting “don’t talk to me” face.
- Enid: Bright, pastel outfit with funky accessories. Extra credit for colorful nails.

Why it slaps: It’s perfect if you and your bestie are polar opposites. Plus, who doesn’t want an excuse to look moody all night without anyone questioning it?
3. Taylor Swift Eras
Swifties, assemble. You and your bestie can go as different eras of Taylor Swift.
- One of you: Reputation era (all black, snake details, red lip).
- The other: Lover era (pastels, glitter, heart motifs).
Why it slaps: You’ll instantly bond with every other Swiftie in the room. Also, if anyone asks what your costume is, you can smugly reply: “I’m in my era.” :)
4. Gossip Girl Queens: Blair & Serena
Channel your inner Upper East Side drama.
- Blair Waldorf: Preppy skirt, headband, sharp wit.
- Serena van der Woodsen: Boho-chic vibes with effortless glam.
Why it slaps: It’s chic without screaming “costume.” You’ll look like you just walked off the Met steps… minus the toxic relationships, hopefully.
5. Mario & Luigi (But Make It Fashion)
Video game icons, but with a glow-up.
- Oversized hats + suspenders (cute crop top version, obviously).
- Add white gloves, fun sneakers, and mustache props (if you’re bold enough).
Why it slaps: It’s nostalgic and hilarious, especially if you dramatically jump around like you’re smashing imaginary bricks.
6. Iconic Pop Duo: Britney & Madonna
Throw it back to that legendary VMA performance.
- Britney look: Sparkly two-piece or schoolgirl fit.
- Madonna look: Black corset, lace gloves, bold accessories.
Why it slaps: Retro, glamorous, and low-key scandalous. People will immediately get the reference, and you’ll look like icons.
7. Winx Club Fairies
Remember Winx Club? Yeah, those outfits were next-level. Time to bring them back.
- Sparkly crop tops, flared mini skirts, glittery wings.
- Bonus points if you coordinate color schemes (Bloom’s red vs. Stella’s yellow, etc.).
Why it slaps: It’s colorful, magical, and a major nostalgia bomb. Plus, glitter makes everything better.
8. Velma & Daphne (Scooby-Doo)
Okay, I know this one’s a classic, but hear me out—it’s always a crowd-pleaser.
- Daphne: Purple dress, green scarf, flawless hair.
- Velma: Orange turtleneck, red skirt, glasses.

Why it slaps: Everyone knows them, and it’s basically a built-in excuse to shout “Jinkies!” all night. Also, if you lose your phone at the party, Velma’s “I lost my glasses!” bit will hit a little too close to home.
9. Euphoria-Inspired Looks
No need to copy a single character—just channel the vibe.
- Think glitter makeup, rhinestones, mesh outfits, neon accents.
- The bigger the eyeliner wing, the better.
Why it slaps: You’ll look effortlessly cool and trendy. Plus, let’s be real—Euphoria makeup tutorials basically kept TikTok alive for a year.
10. Dynamic Villains: Harley Quinn & Poison Ivy
Bad girls unite.
- Harley Quinn: Pigtails, fishnets, baseball bat.
- Poison Ivy: Green bodysuit, leafy details, red wig.
Why it slaps: It’s fierce, fun, and gives you major confidence power-ups. IMO, you’ll feel unstoppable all night.
11. Bratz Dolls
This one’s for the drama queens.
- Oversized platform shoes, mini skirts, heavy lip liner.
- Match your fits to the doll personalities (Yasmin, Jade, Cloe, Sasha).
Why it slaps: You’ll look fabulous and slightly unapproachable—which is exactly the point. ;)
Tips for Pulling Off Any Bestie Costume
Because let’s be real: execution matters.
- Coordinate in advance. Don’t be those people scrambling at Target on Oct 30th.
- Add matching makeup or props. Small details make the outfit pop.
- Commit to the bit. If you’re Harley, swing that bat (responsibly). If you’re Ken, rollerblade into the party like your life depends on it.
Final Thoughts
At the end of the day, the best Halloween costumes aren’t about perfection—they’re about fun, creativity, and showing off your bond with your bestie. Whether you’re channeling iconic duos, living your fairy fantasy, or just leaning into the Barbie multiverse, what matters most is that you feel confident (and get those Instagram-worthy pics, obviously).
So grab your best friend, pick your fave from these 11 trendy Halloween costume ideas for female best friends, and start planning now. Because trust me—nothing screams “Halloween amateur” like waiting until the day of and ending up in a cat-ear headband from CVS. :/
Now tell me… which one are you and your bestie rocking this year?
