Vintage Blazer/Sports Coat Jacket

Vintage Blazer/Sports Coat Jacket. I bought this at an estate sale last week for my husband. I thought it would look great with jeans! It does but it’s too small for him. There are no tags in it. The fabric is a blue houndstooth design with a touch of brown. Pit to pit: 22” Length: 30” Shoulder: 18”
