Club Monaco velvet blazer

Club Monaco gray velvet oversized blazer. Somehow the left sleeve has strange discoloration that I at first thought was intentional but when I did sleeve comparison I noticed it definitely wasn’t. Not sure how but that’s why its priced so low. Other than that it’s in near perfect condition. Boyfriend, oversized fit. 40” bust. Approx 29” length from back of neck. Padded shoulders.
