The perfect mermaid party dress
I ordered the light up dress and my daughter absolutely loved it.The torso area runs a bit long but it still worked out well. 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.

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.

Most beautiful dress
Definitely the show stopper for my daughter 6th birthday. She received compliments all day about this dress. Definitely a must buy and it did come on time. She is wearing I believe a 5/6 but it did have a stretch.

Magical mermaids
Maybe I’m living through my daughter just a wee bit with this cute little dress but she adores it too.The first one I ordered had a few snags on the front and back that made it look like an huge hole and some of the strings in the back were fraying which would have gotten worse had I not exchanged it. The exchange was easy and the second dress didn’t have a snag but still some frayed strings in the back which I just cut back and hoping for the best .If I would allow it , my daughter would live in this dress but I have yet to figure out how to clean it well besides spot cleaning .The headband is a little much for her but maybe she will like it in time .Overall if your little girl loves mermaids this dress is beautiful .

Mermaid Princess
My daughter loved this dress. She’s always loved dressing up in princess dress up clothes since she was a toddler. I got this because she wanted a mermaid themed birthday. We actually ended up using it for Easter Sunday her birthday is in April. It fit perfectly and it was good quality we were able to pass down in the family.

Precioso vestido
La talla es la adecuada, la tela resistente, a mi bb le fascinó su vestido y más cuando lo prendió

Bonito vestido y buen precio
La tallas vienen acorde a la edad, ni grandes ni pequeñas, tiene buena calidad en general, es obvio que no es una prenda que aguantara un uso continuo, pero en general es muy similar fotografía del anuncio, solo tomar en cuenta que la falda no viene en un solo lienzo son varios lienzos de colores y hay que estirarlos uno por uno para que luzca bien.

no es de buena calidad, la composición de la falda es de retazos de tela y se ven mal
Es bonito pero no es de tan buena calidad, la tela de la falda parece retaceria de tela y la parte de arriba en las primeras horas comenzó a deshilarse
