Twin Halloween Costume Ideas for Boy/Girl Twins
Bam Bam & Pebbles

The popular baby duo from The Flintstones would make perfect costumes for a twin boy and twin girl! These would be pretty easy to make yourself, or you can find pre-made costumes on Etsy!
Little Red Riding Hood & The Big Bad Wolf

You’ve never seen a cuter Little Red Riding Hood and Big Bad Wolf! And you can find really easy sewing patterns on Etsy to make your own red cape!
Peter Pan & Tinker Bell

For Disney fans, there are always movie characters to dress up as for Halloween, and many of them are perfect for twins! Peter Pan and Tinker Bell are great examples… so cute!
Superman & Wonder Woman

You can’t deny the fun of dressing up like superheroes, especially for little kids! And for boy-girl twins, who better than two of the most iconic superheroes, Superman and Wonder Woman?
Woody & Jessie from Toy Story

There’s a snake in my boot (and candy in my bag)! If your kids love Toy Story, they’ll love this idea! You can find a Woody costume here and a Jessie costume here!
Dorothy & The Cowardly Lion from The Wizard of Oz

There’s no place like home… except on Halloween, when there’s no place like every house that has candy! For a girl and a boy twin, Dorothy and the Cowardly Lion are perfect, but if your little boy would prefer the Tin Man or Scarecrow, those would be adorable, too!
Luke & Leia

Try to name a more iconic set of boy/girl twins! These are some of the cutest costumes, especially those knitted Leia buns!
Even more adorable would be if Dad dressed up like Darth Vader… which you better believe has been done before, and with great success!

Aladdin & Jasmine

How cute are these Aladdin and Jasmine costumes? Okay, so you don’t have to knit or crochet them yourself, but you can find costumes just like it on Etsy for both Aladdin and Jasmine!
Almond Joy & Mounds

Perfect for a boy and girl twin because, you know, Almond Joy’s got nuts… and Mounds don’t… which is sure to get some good laughs! You can find the onesies here!
Pink Lady & Thunderbird from Grease

Grease Lightnin’! An easy twin costume to put together: all you need are some jeans and plain onesies or t-shirts, and then you can find Pink Ladies and Thunderbirds jackets on Amazon!
Cindy Lou Who & The Grinch

It may only be October, but you know people are thinking about Christmas, too! And these costumes are perfect for twins who love getting into the Christmas spirit: The Grinch and Cindy Lou Who!
Peanut Butter & Jelly

Twins go together like peanut butter and jelly! These make such perfect twin baby halloween costumes, but like many of these ideas, I could see them working just as well for older kids, too!
Raggedy Anne & Raggedy Andy

These classic dolls make the cutest costumes! Striped stockings, overalls, and red yarn wigs like these are (mostly) all you need!
Old Man & Old Lady

What is funnier than dressing up little babies like old people? These easy and cute twin costumes get even better when you add some baby-sized walkers! (Perfect for babies who are ready to move!)
Starbucks Latte & Barista

O-M-G the cuteness factor of these Starbucks-themed costumes! Arguably these could work for any twin combination, but I love the idea of a little boy twin as the barista and the a girl twin as the floofy Starbucks latte!
Cowboy & Cowgirl

You can’t get any more classic than a cowboy and cowgirl duo! Howdy, partner!
Cotton Candy

I put this one here because the pink and blue cotton candy would coordinate well with boy and girl twins, but honestly, this one would work for any combo!
Gender-Neutral Twin Halloween Costumes
Slinky Dog

Here’s a clever way to keep your twins together: connect them with a Slinky Dog costume (the one from Toy Story)! What a fun, original idea for a twin costume!
Two Peas in a Pod

Okay, technically it’s two pea pods, but you get the idea! A great costume idea for littler babies, since it’s made like a bunting and guaranteed to keep your little peas warm!
Two Cuties

Another classic twin pun that makes such an EASY costume! Just buy some orange onesies, beanies, and balloons and plop your little cuties into a box!
Peas & Carrots

A variation on the two peas theme, peas and carrots are another classic duo that make great twin costumes… and the best part is, you can find these exact ones on Etsy!
Finding Nemo & Dory

The example above may be for girl twins, but you can easily alter this cute costume idea for any combination… just substitute pants for tutus and headbands or hats for bows for the Nemo and/or Dory costume!
Pumpkins

Okay, so you may not want to stick your babies into real pumpkins all night, but you CAN find some positively precious pumpkin costumes on Etsy!
R2D2 & C3PO

For Star Wars fans who want to go with a more original idea, there is more than one pair of characters in the movies! R2D2 and C3PO are an inseparable duo that would make great twin costumes!
Salt & Pepper

No, not the rappers… though that could be cute, too… This is another easy one to throw together with coordinating black and white outfits with cute little hats and labels!
Sushi & Soy Sauce

You can’t have sushi without soy sauce, which is what makes these twin costumes such a great pair! Good enough to eat, and best of all, available on Etsy!
Thing 1 & Thing 2

Another classic pair of twins from the memorable Dr. Seuss book, Cat in the Hat! Thing 1 and Thing 2 are rambunctious yet lovable… and totally identical! T-shirts or onesies, striped leggings, and blue wigs make this costume an easy fix!
And if you have older siblings in the mix… add Cat in the Hat!

Buy One Get One Free!

You could really take this idea and run with it with basically any food item… but I love the simplicity of just putting your twins in matching outfits, too! You can find these onesies on Etsy and add your own special touches!

What’s better than one baby chicken? Two, of course! With some craft feathers, chicken hats, and orange leggings, your little chicks will rule the roost!

What makes a more perfect pair than cookies and milk? You can find this exact costume on Etsy!
COOKIES & Milk (With Mama)

And if you really want to go all out, make both twins cookies and Mom gets to be the milk! I love how funny this one is – because, you know, when they’re babies… you literally ARE the milk.
Deviled Eggs

This one is SO funny! Deviled eggs… literally! And like deviled eggs, you can’t just have one… so get some matching white outfits, use half a foam sphere covered in yellow fabric for the yolk, and add some devil horns! You can find the tutorial here!
French Fries & Ketchup

Yeah, these food ones never really get old. French fries and ketchup are yet another perfect pairing that make adorable twin costumes, and this is another one you can find on Etsy!
