This is a spring wetsuit from the wakeboard brand "Liquidforce." It's for women. The size is listed as S, but I, a women's size M (size 9, a little chubby), wore it. I usually wore a rash guard and surf pants in the summer, and a full wetsuit in the colder months, so I didn't use this one very often. There are a few fold marks on the chest. Thank you for your understanding.
