This product got here right when it said it would and just in time haven’t tried it yet in the water but material is very thick and the smallest size is very very small. I’m an extra extra small and most clothing. That’s why I picked the smallest, but it was a little tight. Either way this product seems very nice in the delivery was amazing.

I am so happy, thankful and proud that this type of swimwear exists! My 11 y/o competitive swimmer is a huge fan of this period swim wear! 10/10 absolutely no complaints and has definitely helped the transition into young womanhood without having to skip swim days. Definitely will be recommending to our young women/parent friends! Thank you for being a part of changing the game for young women, wish this was around in my youth!!

Love them. Would love it if they could come in different styles to match different personalities
