Preston and York leather jacket size XL

Preston and York leather jacket Size XL Length 31 Pit to pit 21 Brown Please review pictures for condition and details. Smoke free home. This coat is an excellent condition. It was mine. I only wore it a few times. There is a dark spot on the back. Not sure where that came from. I did not want to attempt to clean it because I didn’t know if it would mess it up and it’s not very noticeable once you have the coat on. Please review picture.
