This is a set of three practice swimsuits. There are two size S and one size M, for a total of three. I wore these for 2-3 years and have been storing them at home since I retired from competitive swimming last year. I wore these when I was 165cm tall. I swam seven times a week and rotated between several swimsuits, so I used these about once or twice a week. They are quite stretched out overall, the elastic has deteriorated, and there is some fabric wear. I'm not sure if they can withstand intense competitive swimming practice, but I'm listing them because it feels wasteful to throw them away. Please understand that these are used, defective items and are being offered at a low price. Thank you for your consideration.
