I purchased this new style for my tall, slender 11- year- old daughter who has a long torso. She loves the fit! We went with a size small, and it fits perfectly. The sizing runs large—she normally wears a large in other bottoms. Great fit for a growing tween! Highly recommend.

5 Mother of two
I needed black suits for swim team for my two girls. I bought the Medium for my very tiny 9 year old. Usually 7/8 is too big for her. I bought the XL for my 11 year old who wears size 14 in a lot of clothes now. It ’s a little bit too snug. She is 98 lbs. and 5 ft. I ’ m hoping they stretch out a little bit with wear. The suits did come quickly, and they are the best priced I could find.

Purchased in store and was very impressed with sales associates
