It is very stretchy and can accommodate nicely if needed.The batteries for the lights were easy to install and easy to hide in the sewn in pouch on the liner of the tutu.The lights are wonderful and vibrant even in day light!The bodice fabric snags easily but has stayed in tact through many dress up sessions. It is one of her favorite to wear and a definite eye catcher. ### ⭐⭐⭐⭐⭐ Fits good. *by on Reviewed in the United States July 2, 2026* This costume is so cute. She loved it so she can play and look beautiful as she says. ### ⭐⭐⭐⭐⭐ Twinkling tails and birthday smiles *by on Reviewed in the United States July 27, 2025* 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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/447390851-koatobbor-girls-mermaid-costume-mermaid-tutu-dress-color-led-light](https://www.desertcart.us/products/447390851-koatobbor-girls-mermaid-costume-mermaid-tutu-dress-color-led-light) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-12*
