Some of my fondest childhood memories stem from my sibling costumes on Halloween. Sure, the mountains of candy were pretty special, but what really filled me with delight was the chance to partner on a costume with my big sister. Ordinarily, she could take me or leave me, but come October, she needed me to be the Raggedy Andy to her Ann or the Wild Thing to her Max.
If you have a couple of siblings to outfit this Halloween, we have a host of coordinating costumes to help take the guesswork out of the upcoming holiday. Read on for over 30 of our favorite Halloween costume ideas for siblings—plus some of the cutest inspiration photos and where to shop to recreate the look for your littles.
TV & Movie-Themed Sibling Costumes
1. ‘The Wizard of Oz’
The Wizard of Oz is full of kids’ costume possibilities, from the story’s four heroes to the witches to just about anyone in Munchkin Land. Any combination of characters will be instantly recognizable and make for one of the sweetest trick-or-treating crews around.
2. Winnie the Pooh & The Hundred Acre Wood Crew
So many sweet characters can be found in The Hundred Acre Wood between Pooh, Piglet, Tigger, Eeyore, and Roo. You can even get pets in on the costume action with this sweet group costume.
3. ‘Mary Poppins’
Another childhood classic, Mary Poppins serves up two adorable costume ideas: the prim and proper Mary and her chimney sweep pal, Bert. Or recreate the iconic animated scene with Mary on the carousel and the dancing penguins.
4. ‘Star Wars’
Whether you and your little ones are fans of the original movies or the new releases, with so many characters, your whole family can get into the fun of a Star Wars-themed costume.
5. The Sanderson Sisters from ‘Hocus Pocus’
Another perfect pick for sister siblings (or a group or family costume), the Sanderson Sisters from hit Halloween flicks Hocus Pocus and Hocus Pocus 2.
6. Thing 1 and Thing 2
There’s nothing quite like a classic. For siblings who go together as well as a cat in a hat, there’s not a better costume out there.
7. ‘Alice in Wonderland’
Send your little ones off on an adventure to Wonderland with this whimsical duo. More siblings? No problem. Choose from a host of characters, from the Queen of Hearts to the Mad Hatter, to round out the group.
8. Cruella de Vil and a Dalmatian
One of the most recognized Disney movies of all time also happens to make an incredible Halloween costume for siblings.
9. Bluey and Bingo
Most kiddos (and parents) can’t get enough of the most lovable heeler pups out there. They’ll be so excited to dress up as their favorite characters this year—and likely won’t want to take off their costumes until Thanksgiving (or later!)
10. ‘A League of Their Own’
Channel this classic ’90s film with costumes that celebrate the professional female baseball league of the 1940s. We dug up uniforms for the Rockford Peaches and the Racine Belles to make a throwback costume for real-life sisters playing onscreen siblings, Dottie and Kit.
We love this costume idea because there are so many ways to make it your own. We love combinations like Elsa and Anna, Anna and Olaf, Sven and Kristoff, and more!
12. Ariel and Flounder from ‘The Little Mermaid’
Ariel needs her friend and sidekick, Flounder, to make this costume extra special.
13. Buzz, Woody, or Jessie from ‘Toy Story’
Buzz and Woody, the original Disney/Pixar duo, makes for an adorable sibling costume. Have more than two kids? Add Jessie, Bo Beep, Rex, or any others!
14. Poppy and Branch from ‘Trolls’
For kids who’d love a creative hair moment, consider dressing sibs as this memorable musical pair from the Trolls movies.
15. Elliot and Gertie from ‘E.T.’
There will be no need to “phone home” as kiddos who love classic movies will feel right at home with these costumes. You can buy props and costumes or DIY with cute outfits your kids can wear after Halloween like a red hoodie (Elliot), black overalls, and a striped shirt (Gertie).
16. The Madrigals from ‘Encanto’
Disney’s runaway hit movie Encanto has plenty of characters for a group family costume—or just the siblings can choose their favorites.
17. The Super Mario Bros.
Kiddos have always been fans of the brothers and their gang, but with the release of the new movie this year, we know they’re going to be more excited than ever for this dress-up opportunity.
18. The ‘Barbie’ Movie
Speaking of new movies, with all of the buzz around the new Barbie movie this year, kids may be excited to dress up as some of the most iconic characters. What’s fun about this option is that they can go the classic route with costumes similar to the original Barbie and Ken, or opt for one of the many fun outfits shown in the new film.
19. ‘Napoleon Dynamite’
Every Napoleon Dynamite family costume needs a Napoleon, but siblings can choose from any one of the memorable cast characters from this 2004 cult classic—like Pedro, Kip, Deb, or Rex.
20. Wednesday and Pugsley
This older sister and little brother pair epitomize Halloween vibes.
21. Peter Pan & Tinker Bell
Sometimes we might wish for Never Never Land where children never grow up. Capture the moment with a Peter Pan and Tink costume.
Creative Sibling Costumes
22. Butterfly and Caterpillar
Perfect for sleepy newborns and their rambunctious big siblings, a butterfly and caterpillar duo is part dress-up fun, part science lesson, and 100 percent cuteness overload.
23. Lion Tamer and Fierce Lion
A circus ringleader costume can double as a brave lion tamer with the addition of a small hula hoop. There are plenty of lion costumes around too, but this handmade option is extra sweet for transforming your little one from toddler to fearsome beast.
24. Astronaut and Alien
Your little ones will be ready for blastoff with these sibling costumes that are out of this world.
25. Jane Goodall and a Chimp
A simple safari outfit can transform into a sibling costume honoring the renowned primatologist Jane Goodall. Anyone who knows a thing about her knows wherever she was, a chimpanzee wasn’t far away!
26. ‘Where the Wild Things Are’
Perfect for your wild little ones on the most fun night of the year! With this costume, they can have a blast bringing their favorite children’s book to life.
27. Honeybee and Flower
There may be nothing cuter than a baby dressed like a honeybee—except if you include a beautiful bloom for good measure.
28. Farmer and Baby Chicken
There’s a reason baby chicken costumes are a dime a dozen come Halloween: they are undeniably adorable. Make it a coordinating sibling costume by encouraging one child to dress as a farmer.
29. Bo Peep and a Sheep
Whether she’s Bo Peep with her sheep or Mary with her little lamb, this costume is too sweet—especially for a little sibling who already follows their older sister around.
30. Firefighter and Dalmatian
There’s not a duo out there quite as iconic as this one—plus it lends itself to a firetruck DIY of their stroller or wagon. They’re sure to feel like heroes all night long in these costumes.
31. Colorful Crayons
What kid doesn’t love crayons? And we love this low-maintenance colorful DIY costume idea for kids.
32. Rabbit and Carrot
What could make for a cuter photo op than your children dressed in these darling ensembles?
33. Ketchup, Mustard, and a Hot Dog
