Purchased at the Harajuku store about 10 years ago. I think I only wore it about 10 times. It has been washed for this listing. No noticeable sweat stains, scuffs, spots, or dirt. I think it's very clean, but please forgive any minor oversights. The fabric is thin, like a dress shirt. Poplin, maybe?
