Some princesses want a dress. Others want tails, fins, and tentacles. Girl's Little Mermaid costumes both! Ariel fans find their legs and keep mermaid style in an Ariel costume outfit with pants, and Flounder fans can give fishy fun a whirl in our playful Flounder dress. Even Ursula looks sweet (and sassy) as can be in our tween Ursula costume dress. From the leading ladies to fave sidekicks, we have stylish character costumes for every fan!

The Little Mermaid wants to walk on land with her own two feet. She wants to try dancing and feel the sand. See what life out of the sea is like. While fans understand the curiosity, we typically want the exact opposite. Especially the youngest fans. There's magic under the sea. There's treasure to be found. Plus, flipping and swimming around with a sparkling tail, seashell jewelry, and a few fishy pals is simply too alluring!

Our collection of girls Little Mermaid costumes let kids feel like part of that world without asking Ursula a favor. In fact, they can be Ursula when you shop the treasures found right here!

From playtime to Halloween, we've got the costumes to give your kiddo that longed for flipper and more. Pick Disney-licensed Ariel costumes for every style. Our Ariel outfit features a glittery top and pants cleverly designed to look like a mermaid tail that keeps your little princess ready to run on land—that Halloween candy is calling, it might as well be gadgets, gizmos, and whozits, whatzits galore!

Of course, if a mermaid dress is more your kid's style, we've got a few to choose from. Our classic Little Mermaid costume has, well, a mermaid skirt attached to a shimmering bodice with chiffon cap sleeves that flutter as playfully as the skirt's flared hems. Meanwhile, any of the available licensed Ariel costume dresses promise to make a splash in any dress-up situation with their purple, teal, sparkle, and easy-accessories.

Ariel isn't the only leading lady though. Ursula offers a fun character for kid's to play with, and our limited kid's Ursula styles do the same! Choose from our tween Ursula costume, a stunning rendering of the live action Ursula's dress, or a sea witch costume that's giving classic princess power to the character.

Or bring a sidekick to the adventure! Our Flounder costume dresses and bubble costumes are favorite ways to ensure the brave guppy isn't left out of the treasure hunt. And our Sebastian costumes, with their plush shells, claws, and exaggerated eyes are as seriously fun as the character himself—but warmer! Even Scuttle, Flotsam, and Jetsam can come along when you shop costumes for each right here!

Whether you're filling a role in your family Halloween costume, ensuring your kiddo can always jump into a Little Mermaid dress-up game with a stocked dress-up box, or looking for a clever Disneybound for your baby, these costumes are sure to please. Shop Ariel costume dresses, full-coverage jumpsuits, and baby carrier covers for every young fan today!
