Hey, squad! Looking to slay this Halloween with your ride-or-die? We've got the ultimate roundup of BFF costume ideas that'll have you turning heads and dropping jaws. Whether you're into classic throwbacks or fresh pop culture moments, these duo Halloween costumes are guaranteed to make you the stars of any party. So grab your bestie and get ready to serve some serious looks.

Jinkies! Nothing says 'squad goals' quite like Daphne and Velma. These mystery-solving babes have been giving us friendship goals since forever, and now it's your turn to rock their iconic looks. 

Whether you're the sassy redhead or the brains of the operation, this costume duo lets you channel your inner detective while looking absolutely fire. 

Plus, who doesn't love a good excuse to rock some groovy 70s vibes? Just don't be surprised if you end up unmasking a few 'monsters' (read: creepy dudes) at the party. Zoinks!

Talk about a magical pairing! Tinkerbell and Wendy are the OG frenemies-turned-besties, and now you can bring that pixie dust energy to your Halloween bash. 

One of you gets to be the sassy fairy with an attitude, while the other rocks that sweet, dreamy storybook-girl-next-door look. It's the perfect combo of naughty and nice – just like your friendship, right? 

Sprinkle some glitter, practice your sassiest hair flip, and get ready to fly high all night long (pixie dust and tequila shots not included).

Life in plastic? It's fantastic! With Barbie fever sweeping the nation, you and your bestie can transform into the ultimate dollhouse duo. 

Channel your inner Margot Robbie and strut your stuff in a sea of pink. For the perfect duo costume get clever with your 'Barbie' personas  - Malibu Barbie, Christie, Fashion Barbie or even Weird Barbie (we see you, Kate McKinnon fans). 

While Barbie might be anatomically impossible, your friendship is 100% real. Now that's something Ken can never compete with.

Want to be bad in the best way possible? Team up as Gotham's most delicious villainesses, Poison Ivy and Harley Quinn. 

This duo screams 'hot girl summer' meets 'chaotic Halloween energy.' One of you gets to rock that killer green lewk while the other goes full-on clown princess of crime. 

It's the perfect costume for besties who love to cause a little trouble (or a lot – we don't judge). Just try not to actually poison anyone or swing any giant mallets, okay?

It's showtime, babes! For the bestie duo that's a little bit dead and a whole lot of fun, how about going full Beetlejuice and Lydia Deetz? 

This classic Burton combo is perfect for the pair who loves to walk the line between quirky and creepy. One of you gets to rock those instantly recognised black-and-white stripes (bonus points for some strategically placed moss), while the other serves goth princess realness. It's the ideal costume for besties who are 'strange and unusual' and proud of it. 

No actually summoning any bio-exorcists at the party, okay? The last thing you need is a sandworm crashing through the punch bowl. Who's ready to shake their dead booties on the dance floor?

Get ready to bring all the feels with this emotional rollercoaster of a costume. Pick your fave new emotions from Inside Out 2 and let your bestie be your perfect mood match. 

Whether you're Envy and Ennui or any other funky feeling, you'll be serving some serious abstract realness. 

It's a great excuse to go wild with colourful makeup and wigs – plus, you can blame any party 'faux pas' on your 'emotion' taking over. 'I don't partake in TikTok videos, I'm Embarrassed!'

Holy plot twist, Batman! This duo costume is hotter than a freshly stabbed corpse (too far?). 

Channel your inner Gen Z icons with these looks straight from Sabrina Carpenter's 'Taste' video. You've got options, babes: go full-on funeral chic with those glam black numbers, serving 'I totally didn't just kill my ex' realness.

Or, if you're feeling extra spicy, why not recreate that Kill Bill-inspired nurse vs. patient showdown? One of you gets to rock that crisp white uniform (hello, Nurse Ratched energy), while the other plays the 'oops, I'm bleeding everywhere' patient. 

It's the perfect costume for besties who love a little playful rivalry – just maybe leave the actual stabbing at home, 'kay? 

With Jenna's certified Scream Queen status and Sabrina's chart-topping bops, you'll be the coolest duo at any Halloween bash. Just be prepared for everyone to ask you to reenact scenes all night long. Time to practice your best 'I'm totally innocent' face.

Let it go? More like let it glow, honey! These Frozen sisters are getting a major upgrade, and it's time for you and your bestie to bring that ice-cold magic into 2024. 

Forget the same old Disney princess look – we're talking Elsa and Anna 2.0, serving future frost realness or walking dead chic. Imagine cyber-punk ice queen vibes mixed with a dash of post-apocalyptic Arendelle. 

Or, if you're feeling extra frosty, why not go full zombie royalty? Nothing says 'sister love' quite like matching decay, right? 

A fresh take on the famous duo is perfect for besties who want to stand out in a sea of basic princess concepts. Plus, it's a killer conversation starter – 'Oh, this old thing? Just my neo-futuristic ice powers, NBD.' 

Whether you're rocking holographic ice crystals or sporting some faux frostbite, this reimagined sister act is guaranteed to have everyone at the party saying, 'Damn, that's cool.' Literally.

Bring it on, Halloween! Channel your inner sports diva with this classic cheerleader duo. 

You and your bestie will be serving legs for days in these iconic blue and white uniforms. It's the perfect costume for those who want to look hot while also having the freedom to bust out synchronised dance moves all night long. 

Don't know any actual cheers? No problem! Just yell 'Go team!' and shake your pom-poms – no one will know the difference after a few cocktails.

For the besties who are 'creepy and kooky, mysterious and spooky,' look no further than the Addams Family's fiercest females. 

One of you gets to be the goth queen herself, Morticia, while the other channels their inner deadpan diva as Wednesday. 

It's perfect for the duo who loves to serve looks darker than their coffee. Plus, you get to practice your most withering stares all night – use them wisely on any unwanted party crashers.

Get ready to defy gravity with this wickedly good costume duo, that just happens to coincide with this year's most anticipated movie release.

Whether you're more of a good witch or a misunderstood green girl, this Wicked-inspired look is sure to cast a spell on everyone. 

One of you gets to float around in a bubble of pink glitter, while the other rocks that emerald shade with pride. 

Just try not to break into a duet of 'For Good' every five minutes – or do, we're not the boss of you!

Aww, deer! (See what we did there?) This adorable forest duo is perfect for the besties who are cute but maybe a little clumsy after a few drinks. 

One of you gets to be the wide-eyed fawn, while the other hops around as the sassy rabbit sidekick. It's a great excuse to wear something cozy and fuzzy, or go high-fashion with an ethereal editorial take.

Just watch out for hunters – or in this case, creepy guys in flannel trying to buy you shots.

Alright, squad, there you have it – the ultimate lineup of BFF duo costumes that'll make your Halloween hotter than a witch's cauldron! 

Whether you're channeling your inner villains, serving up some Disney magic with a twist, or bringing pop culture's hottest duos to life, these costumes are guaranteed to slay harder than a vampire on a midnight snack run.

The best accessory for any costume is your ride-or-die by your side. So grab your bestie, pick your favorite duo, and get ready to own the night like the iconic pair you are. 

And hey, if you can't decide on just one look, who says you can't do a mid-party costume change? Double the outfits, double the fun!

Now go forth and conquer, you fabulous creatures. May your eyeliner be sharp, your wigs be secure, and your friendship be stronger than whatever shapewear you're squeezing into. Happy haunting, witches!
