Woman Within jacket

This gorgeous jacket from Woman Within is a size large which is their 18/20, it's very roomy, and I think it's comparable to a 2x or 3x in other brands. the Shell is 100% polyester, the side panel is 100% acrylic, the lining is 100% polyester. there are some small stains on the sleeve and side which are photoed, I have not tried to launder this since I last wore it to see if they will come out
