Haysandy4 Pcs Girls Mermaid Swimsuit Mermaid Tails for Swimming Mermaid Suit Costume Bikini Set for Big Girls Birthday Gift

I love the fact that the tale has two little snap buttons at the bottom. My daughter loves it.

My daughter is a 4t to 5t and it fit her nice. No sagging.!!! She is a slim fit. I like it cause her feet can move in it. The tail fits amazing!!!!
