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 12 of our favorite Halloween costume ideas for siblings—all readymade and easy as can be. 


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. 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.

3. 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.

4. Mary Poppins

Another childhood classic, Mary Poppins serves up two adorable costume ideas: the prim and proper Mary and her chimney sweep pal, Bert.

6. Star Wars Sibling Costumes

7. Jane Goodall and 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!

8. 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.

9. 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.
