21+ Best Friend Halloween Costumes for 2 (Cute Duo Ideas!)

Every year me and my best friend have the same conversation. It starts in September with “we should totally match this year” and somehow ends the night before the party with us tearing through my closet looking for cat ears.

Last year we actually planned ahead for once and went as Thelma and Louise, and we got more compliments that night than either of us ever got going solo.

There’s just something about showing up as a duo that makes the whole night more fun.

So if you and your bestie are stuck trying to figure out what to be, I got you. I rounded up the best friend Halloween costumes that are easy to pull off, look amazing in pictures, and don’t need a sewing machine or a big budget.

Whether you two are into funny, spooky, iconic or a little bit sexy, there’s a Halloween costume for 2 on this list that fits your vibe.

Some of these are classic duos that everyone will recognize the second you walk in the door, and others are a little more creative so you’re the pair everyone is talking about.

Okay, grab your partner in crime and start scrolling.

Halloween Costumes For Duo

Barbie as The Princess and the Pauper

If you grew up watching Barbie movies, this one is going to hit you right in the childhood.

It’s super easy to put together too, all you need is a white corset, a satin mini skirt in pink for the princess and blue for the pauper, plus a ribbon choker for each of you.

Add a sparkly tiara for Anneliese and a little flower crown for Erika and you’re done. The tulle ribbons on the arms are a cute extra touch if you want to go the extra mile, and every girl at the party will know exactly who you are.

Serena and Blair from Gossip Girl

XOXO, this one is probably already in your closet. All you need is a white button down, a navy or black skirt and a tie for each of you.

Serena wears her tie loose and messy with big wavy hair, and Blair keeps hers in a perfect little bow with her signature headband.

A bold red lip for Blair is the finishing touch. It’s one of the easiest best friend costumes on this list, and it’s perfect if you two are always deciding who’s the “Serena” and who’s the “Blair” anyway.

Magician and Her Bunny

This one is so cute and you can pull it together in like 20 minutes.

The magician wears a black corset or vest, black shorts, a top hat and white gloves, then tucks a few playing cards into her top and pocket for that “pick a card” moment.

The bunny just needs a white slip dress and a fluffy pair of bunny ears. Hand her the magic wand and you’ve got the most adorable duo at the party. Bonus points if you pretend to pull her out of a hat all night.

Cleo de Nile and Clawdeen Wolf from Monster High

Calling all the Monster High girls! This duo is such a fun throwback and you can find most of it on Amazon or at the thrift store.

Cleo wears a turquoise crop top, a gold sequin skirt, lots of gold jewelry and chains, plus some gold tinsel and a black streak in her hair.

Clawdeen goes for a leopard print top, a purple mini skirt, purple knee socks and a pair of wolf ears. Keep the makeup bold and glam, because these two never did anything halfway.

Little Red Riding Hood and the Wild Cat

This is a fun twist on the classic Little Red Riding Hood and the Big Bad Wolf. Red wears a black bodysuit, black leather shorts and a red hooded cape, then draws a few scratch marks on her cheek like she just barely escaped.

Her bestie goes for a black lace corset, black shorts, leopard ears and some spots with a little nose drawn on.

Both looks are super easy to put together, and the scratch marks make it look like you two have a whole story going on.

F1 Race Car Drivers

This one is trending hard right now and it’s so easy to copy. Grab a pair of vintage racing jackets, red crop tops, black leather or denim shorts and some knee high black boots.

A red lip and a pair of tiny sunglasses pull the whole look together. If you can’t find racing jackets at the thrift store, Amazon has a ton of them, and you’ll probably end up wearing yours way past Halloween.

Great Gatsby/1920s Flappers

If you two love an excuse to go full glam, this is your costume. Each of you wears a fringe flapper dress, one silver and one rose gold looks so pretty together, then add a feather headband, long satin gloves and a feather boa.

Finish it off with pearls, some vintage waves in your hair and a bold lip. It’s elegant, it photographs beautifully, and you can find almost every piece in one Amazon order.

Victoria’s Secret Angels

Channel the iconic runway show with this one, it’s glam, girly and so easy to pull off. Grab a rhinestone bra top or bedazzle one yourself, then pair it with pink satin and lace shorts and a pink satin robe.

The striped robe is such a cute nod to the classic Victoria’s Secret look. Add a pair of white feather angel wings, big bouncy blowout hair and a glowy makeup look and you two are ready to walk the runway.

Tiffany and Brittany Wilson from White Chicks

If you and your bestie love a good comedy, this one is going to get so many laughs.

One of you wears a pink houndstooth skirt set with pearl hair clips and carries a tiny pup, and the other goes for a pink graphic tee, a denim mini skirt, a cropped denim jacket and a red shoulder bag.

Grab two long, curly blonde wigs and a glossy pink lip for both of you. If your bestie is a guy, even better, because that’s the whole joke of the movie. Just be ready to quote it all night long.

In-N-Out Workers

This is one of the funniest and cheapest costumes on the list. All you need is a white button down, a red mini skirt, white socks and some red and white sneakers.

The best part is the paper hats, you can usually just ask for them at your local In-N-Out for free.

Add a headset, a guest check pad and a pen tucked in your waistband, and you two are ready to take everyone’s order. Animal style, of course.

Thing 1 and Thing 2

This is a classic best friend costume for a reason, it’s so easy and everyone knows who you are right away.

Grab two red mini dresses, red vinyl if you want to make it a little extra, and stick a white circle on each one with “Thing 1” and “Thing 2” written in black.

Add blue wigs, red and white striped knee socks and white boots. A cardboard fishbowl cutout is a fun prop for photos, and you can make it in about five minutes.

Alice and the Cheshire Cat

This Alice in Wonderland duo is so cute and you can make it as simple or as extra as you want. Alice wears a light blue top, a little white skirt or apron, white thigh high socks with black bows, Mary Janes and a black bow in her hair.

The Cheshire Cat goes all out with a purple corset, pink and purple striped tights and sleeves, fuzzy leg warmers and pink cat ears.

Don’t skip the purple face paint and the big grin, that’s what really makes the cat. You two will be the most whimsical pair at the party.

Ethereal Fairies

If you two want to look like you just floated out of an enchanted forest, this is the one. Each of you picks a soft color, like blue and mint green, and wears a beaded or embellished crop top with a sheer, flowy skirt or wrap.

The big iridescent wings are the star of the show, so go as big as you can.

Finish with strappy lace up sandals, a dainty headpiece and some shimmery makeup. This one takes a little more effort than the others, but the photos are so worth it.

Sailor Girls

Ahoy! This one is cheap, cute and you probably have half of it already. Each of you wears a white tube top or bandeau with black and white striped shorts, then ties a navy and red silk scarf around your neck.

Top it off with a pair of sailor hats, which you can find for a few dollars on Amazon or at any party store. Practice your salute and you’re ready to set sail.

Fairy and Butterfly

This is a super easy and girly duo that looks so pretty side by side. The fairy wears a sparkly mint green corset dress with iridescent wings and carries a little wand.

The butterfly goes for a pink satin corset dress with big pink and black monarch wings.

Both of you can finish the look with strappy heels, a sleek high ponytail or messy bun and some glowy makeup. You can find both sets of wings on Amazon, so this one comes together fast.

Women in Black

This is a fun girly twist on Men in Black, and it might be the easiest costume on this whole list.

All you need is an oversized black blazer, a white button down, a black skinny tie, a black mini skirt or shorts and some black boots.

The sunglasses are a must, the smaller and sleeker the better. Bonus points if you carry around a little toy alien or a “neuralyzer” pen to flash at people all night.

The Shining Twins

If you want something a little creepy without the gory makeup, this is it. Grab two matching light blue dresses with puff sleeves, tie a pink ribbon around your waists and add white knee high socks and black Mary Janes or sneakers.

A little white bow in your hair finishes it off. The secret to nailing this one is the pose, so stand perfectly still, hold hands and find a long hallway for your photos.

Saying “come play with us” in a creepy voice all night is optional, but highly recommended.

Pete Davidson and Timothée Chalamet’s SNL Rappers

If you two are huge SNL fans, this one is going to be a hit with anyone who’s seen the Rap Roundtable sketch.

One of you is Pete’s character Guaplord in a baggy orange hoodie and sweatpants, a blue wig, round glasses and a chunky gold chain.

The other is Timothée’s character in a white tank, white baggy jeans, a hot pink wig and a big gold dollar sign necklace.

Draw on some fake tattoos with eyeliner, especially on the face and arms, and you’re done. Yell “skrrt” all night for the full effect.

Willy Wonka and Violet Beauregarde

This Charlie and the Chocolate Factory duo is so fun and super easy to DIY.

Willy Wonka wears a black lace bodysuit, a burgundy velvet blazer, a black top hat, white round sunglasses, purple gloves and knee high boots, then carries a cane.

Violet goes all blue with a matching tracksuit and sports bra, and dabs a little blue or purple face paint on her nose and cheeks like she’s mid blueberry transformation.

Keep a pack of bubble gum on hand for photos, because blowing a big bubble is what really sells it.

Fire and Ice

If you and your bestie are total opposites, this costume was made for you. Fire wears a red sequin bodysuit with orange flame details, a sheer orange tulle train, a flame crown and red strappy heels.

Ice goes for a sparkly blue corset bodysuit, a sheer snowflake cape, an icy crystal crown and silver glitter heels, and a silver wig takes it to the next level.

Keep the makeup glam with a bronzy glow for Fire and shimmery icy eyes for Ice. It takes a little more effort than the others, but you two will look straight out of a fantasy movie.

Padmé and Princess Leia from Star Wars

May the force be with your bestie! This all white Star Wars duo is so easy because you can make it with basics you probably already own.

Padmé wears a white long sleeve crop top, white shorts, a tan utility belt or fanny pack and white boots, then carries a toy blaster like a Nerf gun.

Leia goes for a white long sleeve mini dress with flowy sleeves and a silver belt, which you can DIY with some silver circles on a white belt. Pull your hair into two low buns for Leia and you two are ready for the dark side of the party.
