Atelier Noir by Rudsak winter coat

Not to be confused with the exact same coat I have in size S! Down- and feather-filled black 3/4 length coat from Atelier Noir by Rudsak. Leather trim. A beautiful and warm coat in very good used condition except for: 1) a button on the inside of the coat which is hanging by a thread, and 2) a mark on the back of the right sleeve (the last 2 or 3 photos are my attempts to show this in the worst possible light). Size M; measurements in photos.
