The size is XL. I've worn it once, but I wore it over an undershirt, so it wasn't worn directly on the skin. Also, I didn't sweat in it, so it hasn't been washed. There are no noticeable odors or stains, but there may be minor scratches from wear and creases from storage. Please understand that this is a used item. To prevent any issues, please ask any questions before purchasing. To save on shipping costs, I will fold it up small and ship it via Nekopos. Thank you.
