The fit is like a size S-M. I'm selling it because my arms no longer fit after weight training. I don't think there are any noticeable stains, but I apologize if I missed anything. If you're concerned, feel free to request additional photos! It's a knit jacket. The size is XS (XS in America). It's also stretchy. Authentic, purchased at a department store. The photos from the second image onwards are of the actual item.
