I bought this about three years ago. I used it when I started playing soccer. Since I haven't used it much, there aren't any noticeable stains. The size is 130. It's a set of: White tank top Green underwear White shorts White inner shorts? (Photos 1 and 2 from the end) I don't quite remember the inner shorts, but they were a tight fit, so I think I wore them under the shorts. I'm sorry, I don't remember exactly how to use them. I'd appreciate it if you could consider these as a bonus. Thank you for looking.
