      Halloween is basically the Mia Belle Girls Olympics. Every year we design Halloween costumes for girls that skip the itchy fabric and flimsy plastic and instead look like something out of her favorite story: twirl-worthy tutu dresses, sparkly wings, wicked witch looks, and costumes cute enough to wear all year.

      Shop by vibe: go royal with our princess costumes, delightfully creepy with our scary Halloween costumes, or full magic with fairy and unicorn costumes. Shopping for the littlest one? Our toddler Halloween costumes come in sizes 2T to 5T. And because matching is kind of our thing, don't miss matching family Halloween costumes for mommy-and-me (and sibling) photos that win the group chat.

      Every costume comes in girls sizes 2T through 12, with fast shipping so it arrives before the big night. Pair any look with our Halloween accessories to finish it off.
