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 Halloween 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, keep scrolling for dozens of coordinating costumes to help take the guesswork out of the upcoming holiday. This list of sibling costumes includes options from pop culture, nostalgic movies, kid-favorite shows, storybooks, nursery rhymes, nature, and more! We’ve broken some of the list down to sibling costumes for boys and girls, but, of course, any child can dress in their favorite costume on Halloween, no matter their gender. Read on for over 50 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.

Boy and Girl 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. With one sister as Dorothy, any combination of characters will be instantly recognizable and make for one of the sweetest trick-or-treating crews around.

3. Bluey and Bingo

While Bluey and Bingo are sisters, we think any sibling duo can dress up as the most lovable Heeler pups— Bluey, Bingo, or cousin Muffin (a new costume this year!). And they likely won’t want to take off their costumes until Thanksgiving (or later).
