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 14 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.

10. Lion Tamer and Fierce Lion
