LED Mermaid Princess Dress

Mermaids appear in mythologies from all around the world — from ancient Greece to Japanese legend, from Andersen’s fairy tales to Disney films. Everywhere, they symbolise the same thing: the mystery of the water, boundless freedom, and a beauty unlike any other.

It’s no wonder children are so enchanted by them. Your daughter may already have her very own favourite mermaid. And now, she can become her.

The fabric that makes this mermaid costume truly magical

The tulle on this mermaid costume has something special about it: it’s iridescent. Depending on the angle and the light, it shifts from purple to turquoise, from pink to gold — just like a mermaid’s scales beneath the water.

This effect, combined with the multicoloured LED lights that illuminate the skirt from within, creates a visually stunning result. This is not a dress you forget easily. And your daughter won’t want to forget it either.

For little girls who live as mermaids all year round

Has your daughter been in her mermaid phase for months — maybe even years? She swims like a mermaid, styles her hair like a mermaid, and draws mermaids on every notebook she owns. This costume is made for her.

And unlike some costumes that only come out once, this one is so beautiful it’ll be pulled from the wardrobe again and again. For Halloween, a birthday party, a show, or just a rainy Tuesday that deserves a little bit of magic.
