I used to go to the pool once a week for fitness. The size is listed as 9M. I believe it's around a size 150-160cm. My daughter is in 5th grade. There are no stains or scratches, but since my daughter wore it, I think there is some sign of use. The area around the hips doesn't seem to have much rubbing. I believe it can still be used, but please only purchase if you understand this. A slim-fit, open-back swimsuit for comfortable wear and optimal for swimming. - Brand: Reebok - Color: Black/Orange/White - Type: Swimsuit - Design: Slim fit - Features: Open back design Thank you for looking.
