Awesome dressy blazer

It looks like very dark, almost black denim (sleeve close up with black shoe for comparison). Has a button closure right at waist but be mindful of the size as the double fabric waist band with button is not stretchy and will try to break your last rib. Waist laying flat is 13". Although it looks lovely when buttoned, it's also nice unbuttoned. The jacket-'cept for waist- has a bit of stretch to it. I think I got this in Canada.
