What our customers are saying
Generated by AI from 37 most recent customer reviews
Last updated yesterday
Customers say this swimsuit is a game-changer for young swimmers. Many reviews mention the comfortable fit and stylish appearance. The suit runs small initially, with several noting it's less stretchy than standard swimwear. While competitive swimmers appreciate its functionality during practice and meets, some mention the fabric loosens when wet. Common feedback includes praise for the flattering design, though sizing can be tricky to get right. Many reviewers mention purchasing multiple suits after positive experiences.

- Rated 4 out of 5 stars8 months agoSmall fit
This is a cute suit and seems very well made, however it definitely runs small. I ordered a small for my 13 yo daughter and it's quite tight on her shoulders and doesn't have much stretch. Unfortunately it was a final sale, so hoping it gives a bit once wet.
ConahVerified BuyerReviewingTeen Period Swim Freestyle One-Piece - Rated 5 out of 5 stars9 months agoGreat teen swim
My daughter loves her swimsuit. We purchased, she wore it 3 times, left for 2 weeks summer camp and got it stolen. She was so bummed and disappointed, it was really the only thing that made her feel confident enough to swim during her periods. We then had to purchase a second one. But it is worth every penny.

Anaëve L.Verified BuyerReviewingTeen Period Swim Freestyle One-Piece - Rated 3 out of 5 stars2 years agoNot for an athlete swimmer
Size runs on the smaller size. Material is not very stretchy. My daughter feels uncomfortable wearing this for her swimming practice.
