## Description

desertcart.com: Koatobbor Girls Mermaid Costume Mermaid Tutu Dress Color Led Light Up for Halloween Birthday Party 3-8Years : Clothing, Shoes & Jewelry

Review: Twinkling tails and birthday smiles - This dress is pure enchantment. The purple bodice with starfish and flower details, combined with the light-up multicolor tutu skirt, makes it an instant favorite for birthday parties, Halloween, or just backyard mermaid missions. I love the bonus LED feature, which adds sparkle without being too bright—just enough to wow without overwhelm. The matching seashell headband completes the look and fits snugly (yes, it’s adjustable!), making the whole set feel like an undersea celebration in motion. At 4.6 stars across 481 reviews and 300+ purchases this month, it’s clearly delighting lots of little sea explorers. Ours was first scooped up in February and it still makes waves in the dress-up bin. If you’re looking for a costume that blends princess charm with magical flair, this one floats to the top—and it’s earned every shimmer.
