    Small 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.

    Great 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.

    Perfect for my active teen!

    My daughter wanted a suit for swim team. This one works great for practice or meets when on her period.

    Fits nice, not 100% leak proof

    It looks and feels good, however is not 100% leak proof. Good enough though!

    My daughter LOVES this!

    My daughter loves this bathing suit! The fit is perfect, the color is flattering, and you can't tell it's a period bathing suit. I'm very happy with this bathing suit and will definitely continue to purchase more bathing suits from KT by Knix!

    Teen Period Swim Freestyle One-Piece

    + : It has an excellent quality.

    - : The body has a double lining which makes it heavy for her to swim during her training.

    Not 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.
