I bought this about a year ago for badminton. I used it for about 2 months. There are no noticeable stains, but please refrain from purchasing if you are concerned, as it has been stored by an amateur. I don't remember what size I bought it in at the time, and the tag doesn't have the size listed. I am 170cm tall and of slim build, and it's a little big on me, so I think it's probably a Large. I apologize for being vague, but thank you for your understanding. Please feel free to comment if you have any questions.
