Over the years I’ve dressed up 30+ times and I love being your resource for all things Halloween including costumes, nails & more!

BEST FRIEND HALLOWEEN COSTUMES

Here you’ll find couples costumes, duo costumes, costumes for the whole group and more. If you love a pop culture reference then you’ll love all of these best friend halloween costume ideas. Most of these costumes can be thrifted, DIYed pieced together from pieces already hanging in your closet. So grab your partner in crime and start planning your costume for next Halloween.

American Girl Doll Costumes

These American Girl Doll Costumes may just be our best work ever! Not only are the American Girl Dolls the perfect inspiration for ULTIMATE Best Friend Halloween Costumes, I’ve literally never seen someone dress up as them before! There are plenty of doll options so this is the perfect costume idea no matter if you’re dressing up with 4 friends or 14 friends! We kept it with most of the original American Girls – Kirsten, Kit, Samantha, Felicity and Molly – but there are so many characters to choose from.

The Chilling Adventures of Sabrina Costume

Who doesn’t love Sabrina Spellman? I was huge fan of the original Sabrina the Teenage Witch from the 90s with Melissa Joan Hart, but am an even bigger fan of The Chilling Adventures of Sabrina Netflix series! Sabrina, the Weird Sisters and Lilith were super fun to dress up as! I mean who doesn’t love a girl group made up a witches and the Queen of Hell? If that doesn’t scream the perfect spooky Halloween group costume I don’t know what does!

Heathers

If your group of friends loves classic 80s movies then look no further than Heathers for your best friends Halloween costume for this year! Scour the your favorite thrift store for blazers with shoulder pads, pleated skirts and loafers and pick up a few extra cans of hairspray for teasing. I love that this is more of a “if you know you know” creepy costume! If you love costumes inspired by movies you’ll love this post.

Romy and Michele

If you haven’t seen Romy and Michele’s High School Reunion, drop everything and watch it immediately, because this duo might be the most iconic best friend costume of all time. Grab a bubblegum pink dress for one of you and a baby blue dress for the other, tease your hair a little and you’re instantly recognizable. Bonus points if you tell everyone you invented Post-Its.

The Craft Costume

Looking for another iconic 4 person Halloween girl group costume that’s not Heathers, why not dress up as the ladies from The Craft! Not gunna lie this is probably the OG Ultimate Girl Gang Halloween costume and if you manage to complete a “light as a feather, stiff as a board” party trick wherever you’re going I guarantee you’ll win best dressed!

Toy Story Duo

Whether you go as Woody and Buzz or Jessie and Bullseye, Toy Story costumes are a great pick if you want something nostalgic that can work as an iconic duo bff costume and also works beautifully as a bigger group costume down the line.

The Handmaid’s Tale

Want to freak everyone out this Halloween? Grab your best gal friends and a bunch of Handmaid’s Tale cloaks and just walk around the party not speaking for the first hour.

Scream

This Scream costume works best as a two person costume and the only question you and your bestie need to ask yourselves is who’s going to play Drew Barrymore’s Casey Becker and who’s going to chase her around all night as Ghostface! Scream is a classic scary Halloween costume that truly never gets old.

2 Broke Girls

If your friendship involves a lot of inside jokes about being broke and ambitious at the same time, Max and Caroline from 2 Broke Girls are a fun, underrated pick. Yellow dresses, red aprons and a little bit of attitude are all you need. It’s easy to DIY and super recognizable.

Dark Disney Princesses

Why be a Disney princess when you can be a group of dark Disney princesses? Grab your friends and dress up as your favorite childhood princess, whether it be Cinderella, Snow White, The Little Mermaid or someone else, but with a twist!

Disney Villains

And if princesses aren’t your thing, why not be Disney Villains!! We had way too much fun dressing up as Ursula from The Little Mermaid, Cruella de Vil from 101 Dalmatians and Maleficent from Sleeping Beauty. (Shop my Ursula costume)

Elsa and Anna from Frozen

This one is a classic for a reason! If you and your bestie are the kind of dynamic duo that’s always there for each other no matter how cold things get, dress up as Elsa and Anna. One blue gown, one green and purple cape dress, and you’re set. This is also a great one if your group grows, since you can easily add Olaf or Kristoff into the mix.

Great Gatsby

Going to a fancy Halloween party? Then look no further than these Great Gatsby inspired flapper costumes for your group costume! Everyone can add their own flair to their look, but collectively you’ll look like the best dressed group!

Ghostbusters

Whether you’re channeling the original Ghostbusters from the 80s or the female led 2016 version, this is such a fun group costume to dress up in! You can DIY these jumpsuits and backpacks or just buy them like we did. Either way I guarantee everyone you encounter will love this group costume idea!

Daphne and Velma from Scooby-Doo

This duo is endlessly easy to put together and endlessly recognizable. Grab an orange turtleneck and purple skirt for Velma, and a lavender dress with an orange scarf for Daphne, and you’ve got yourselves a mystery-solving best friend costume that works for every age group.

The First Wives Club

If you’re looking for a niche girl group costume look no further than The First Wives Club! This costume is perfect for 3 people so grab your 2 besties and an all white look! Bonus points if you learn the choreography from the “You Don’t Own Me” scene!

Powerpuff Girls

Another perfect costume for 3 people would be the Powerpuff Girls! You can easily create these easy halloween costumes with basic cotton Amazon dress so this is a perfect last minute costume that is still unique!

Alice in Wonderland Duo

If you and your bestie love a storybook costume, Alice in Wonderland is endlessly flexible. One of you can go as Alice in her iconic blue dress while the other goes as the Mad Hatter or Cheshire Cat. This costume works for literally any age and any group size, so it’s a great one to keep in your back pocket.

Music Legends

This one can be a group costume, but also a solo costume! There are so many music legends you can dress up as – Freddy Mercury, Elton John, David Bowie, Selena, Stevie Nicks, Elvis Presley, Slash and more!

Stranger Things Duo

Stranger Things has given us so many iconic pairings over the years and honestly any combo works, but Eleven and Dustin might be my favorite. Grab a pink dress and a blue jacket for Eleven and a baseball cap with a graphic tee for Dustin and you’ve got an instantly recognizable duo that’ll have every 80s kid at the party geeking out.

Troop Beverly Hills Costume

No matter if you have 1 best friend or 10 the Wilderness Girls from the 80s classic, Troop Beverly Hills, is the perfect girl group Halloween costume! You’ll have to fight who gets to play the glamorous Phyllis Nefler, but other than that this is such a fun nostalgic costume.

Dumb and Dumber

If your friendship is more “we make terrible decisions together” than “we’re superheroes,” Lloyd and Harry’s bright orange and blue suits from Dumb and Dumber are endlessly fun and ridiculously easy to spot in a crowded party. This is also a hilarious option for a couple Halloween costume.

Riverdale

I love a Teen TV Drama and Riverdale was the best one of the past few years! It’s creepy, entertaining and filled with twists and turns. Megan and I dressed up as Cheryl Blossom and Betty Cooper, but there’s plenty more tv show characters like Archie, Jughead and Veronica you can add to the group costume!

Wayne and Garth from Wayne’s World

If you’re looking for quite possibly the easier, but still beyond amazing costume for October 31st, Wayne and Garth from Wayne’s World never gets old. All you need is a white t shirt, jeans, a hat, plaid shirt and maybe some drum sticks.

Phil and Lil from Rugrats Costumes

These Phil and Lil Rugrats costumes were super easy and perfect if you’re looking for a last minute DIY costume! And what’s even better is that if you have a whole bunch of friends looking for an awesome group costume you can combine this duo costume with the below costumes and dress up as the whole Rugrats gang!! ((And if you do, pretty please tag me in your photos. I’d love to see your costumes!))

Chuckie and Angelica from Rugrats (Bonus Costume Tommy)

I swear Rugrats are making a comeback this year, because these Chuckie Finster and Angelica Pickles duo Halloween costumes are hot, hot, hot! These were SO fun to make and wear, plus they’ll work for pretty much any Halloween occasion (crazy party, trick or treating, etc.) and they’ll work for any age! Get all the details on this Rugrats costume right here!

Spice Girls

No matter how old we get the Spice Girls will forever be an iconic girls costume. Grab you 4 besties and pay tribute to the original girl group. The hardest part will be deciding who plays who!

Lucy & Ethel from I Love Lucy

This Lucy and Ethel costume is definitely our most popular best friends Halloween Costume so I knew I had to include in this round up. This costume is great because you more than likely already have everything you need to dress up hanging in your closet already and because it’s really recognizable! Everyone will know who you are! Get all the details on this I Love Lucy Costume here!

Before & After Julia Roberts from Pretty Woman

This Pretty Woman costume from last year was a hit! Another super recognizable costume that everyone will wish they thought of. I’m all about 90’s themed costumes. Especially if you’re headed to a party with people that grew up during that time. Get all the details on this Julia Roberts costume here!

Hocus Pocus

If you’re looking for a trio outfit, nothing is more iconic than the Sanderson Sisters from Hocus Pocus. One year I dressed up as the 2020s version of Sarah Jessica Parker’s Sarah Sanderson and it was so funny. You can also expand on this Halloween costume by adding a Dani and Max Dennison and an Allison. As far as Halloween movies go, Hocus Pocus is one of the best and this costume will never get old to me.

Samantha and Endora from Bewitched

Looking for a niche costume? This Bewitched duo costume is for you! It’s also perfect if you’re looking for something modest and not revealing to wear to an office Halloween party. Get all of the pieces to recreate this costume here!

The Grady Twins from The Shining

If you and your bestie lean more toward spooky than cute, the Grady Twins are about as creepy and iconic as a horror duo gets. Matching blue dresses, white tights and a blank stare are honestly all you need to send a chill down everyone’s spine at the party.

Peg & Kelly Bundy from Married with Children

This Married With Children themed costume was definitely one of the funniest costumes ever. We definitely got a lot of stares and confuse faces, but once people realized who were were they loved it. See more photos of this hilarious costume here!

Cher & Amber from Clueless

Clueless is CLASSIC Halloween content. Instead of going for the plaid Cher & Dionne costumes, we decided to stray from the norm. We created costumes from the classic “balls fly at my nose” scene!Athletic ability not required…get all the details here!

Wilma & Pebbles from The Flintstones

The Flintstones are another classic Halloween costume that’s perfect no matter how many people you’re dressing up with! You can be Wilma and Pebbles like we are or incorporate in Fred, Bamm-Bamm, Betty and Barney! Get everything you need to recreate these costumes here.

Chucky & Bride of Chucky from Child’s Play

Who else grew up watching all the Child’s Play movies? Check out more photos of this costume here!

Harley Quinn and Poison Ivy

For a slightly edgier comic book-inspired costume, Harley Quinn and Poison Ivy make an unforgettable pair. Red and blue for Harley, green for Poison Ivy, and you’ve got one of the most photographed duos at any Halloween party.

Reba McEntire & Dolly Parton

This Reba and Dolly best friends Halloween Costume was definitely one of our more ridiculous ideas! You can find all the pieces you need to create these costumes in your closet. But you need to be comfortable enough to stuff your shirt with two balloons ((insert laughing face emoji)). See more photos of this hilarious costume here.

Batman and Robin

For a more superhero-leaning duo, Batman and Robin never misses. Whether you DIY these with spandex bodysuits and capes or buy the whole set, this is one of those costumes that photographs incredibly well no matter where you’re headed for the night.

Punny Food Pair Costumes

Sometimes the easiest best friend costume is the punniest one! Ketchup and mustard, peanut butter and jelly, salt and pepper, sun and moon…these punny pairs are all basically foolproof. Grab a red shirt and a yellow shirt (for ketchup and mustard), or a purple shirt and tan shirt (for PB&J), add a few simple labels or accessories, and you’re done. These are perfect if you’re short on time but still want something that’ll make people smile.

“Miss Universe” Halloween Costume

There are funny Halloween costumes. Then there are funny “punny” Halloween costumes, and this “Miss Universe” Halloween costume is just that. This “Miss Universe” costume is probably my most popular solo Halloween costume I’ve ever done. But there are a ton of more costume ideas in the Halloween section of my blog!
