I have kept this at home. There are no noticeable stains, but it has been used to a certain extent. There's no problem wearing it when cheering. In the second photo, there is a 3mm stain from a marker on the bottom right of the button. It's not very noticeable. It has been used, but it can still be worn. The size is listed as free. It gives the impression that it would be a bit roomy even for an adult man. Material: Body ・ Polyester: 100% MIZUNO
