Looks awesome! Superb throughout with no holes or stains, no missing buttons, really sharp! This is a black denim blazer, the fabric tag is pretty well faded out almost completely, can't make out the fabrics but just generally speaking it's stretch denim of some kind, likely mostly cotton and a small percentage of spandex. Features a two button front style, single breasted with a pair of flap front waist pockets, seams that extend all the way to the shoulders from there - kind of different and gives it a very modern stylized look. There's no breast pocket, also classic traditional notch lapels. The sleeve cuffs have a single button each; the interior is fully lined with a fine gray and black striped lining, nice interior labels overall and hanger loop. Lastly it has a single vent in the rear.
