I've worn this quite a bit, but it's still in good condition with no noticeable stains, so I think you can still wear it. It's a size M, but the fit is quite loose. The chest area is lined. The actual color is closest to the color of the fabric in the top part of photo 6. I've folded it and stored it in the closet, so there are creases throughout. I'm also listing this on other sites, so I will remove this listing if it sells there.
