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.

Absolutely beautiful
My granddaughter wanted to be a mermaid for Halloween. This dress was soft in the upper chest so she didn't feel itchy! Oh, it lights up with batteries in a little battery pocket

Special!
This made a 5 year old little girl over the moon happy. Absolutely adorable, marveled by all who saw her wear it constantly! She did not want to take it off. For the price, absolute find!

It’s perfect for your mermaid loving baby!
It’s the cutest thing I’ve ever seen! My daughter is going to go crazy for this birthday dress. We’re having her birthday party in Costa Rica where her TT is going to be a mermaid! So this is perfect to make her feel beautiful in the cutest light purple! Material is double lined which I love, inside has a silky texture. Batteries are easy to put in comes with a pocket to put the pack I. And the crown is just the cherry on top! Highly recommend! 🥰
