Purchased from a used clothing store. I wore it for one season, but it became a bit tight due to changes in my body shape, and I've kept it stored at home for several years. It has the typical signs of wear and tear for used clothing, but there are no noticeable stains. The size is marked as M, but I think it's equivalent to a Japanese size L. The name on the label has been blacked out with a marker. Sleeve length is measured from the armpit to the cuff.
