I had it professionally cleaned and water-repellent treated each time. I haven't worn it very often, so I'm putting it up for sale. I think it can be worn by people from junior high school age to women's sizes. It has been cleaned, but I apologize if there are any overlooked stains. Please understand that all sales are final, and no claims will be accepted. Thank you very much (*^^*)
