This enchanting Ariel dress lets your little one dive straight into the magic of the Little Mermaid. Inspired by Disney’s Princess Ariel, this kids’ costume brings her under-the-sea world to life with a glittery, shimmering design that sparkles with every step. Soft, flowy, and easy to wear all day long, it is made for twirling, playing, and endless dress-up adventures. It comes in true kids’ sizes 3T, 4T, 5, 6, 7T, 8, and 10, so finding her perfect fit is simple.
Every detail of this Ariel dress is designed for maximum princess magic and all-day comfort. The shimmering bodice and flowing skirt catch the light beautifully as she moves, giving her that mermaid glow every little Ariel fan dreams about. The sparkling details are securely attached for lasting wear, and the dress holds up beautifully to repeat performances, school plays, and countless twirls around the living room. The lightweight, flowy design is easy for kids to put on and take off by themselves, which means more playtime and less fuss for parents. Whether she is heading to a birthday party, a Disney vacation, or just ruling her own backyard kingdom, this costume keeps her comfortable from morning to night.

Toddlers, little girls, and big kids can all find their perfect Little Mermaid look. We recommend choosing her usual clothing size for the most comfortable fit, and checking the size chart if she is between sizes. Every size is cut with room to move, so she stays comfortable whether she is dancing, posing for photos, or hunting for treasure under the sea.
This versatile Ariel dress shines at every event on your calendar. It makes a show-stopping Halloween costume, a dreamy birthday outfit, and an unforgettable Disney trip dress. It is also wonderful for themed parties, family photo shoots, school dress-up days, library story time, and princess-themed playdates with friends.
