Black slightly cropped blazer

Pit to pit in the back: ~19.5 inches From end of collar to bottom: ~19.5 inches Stylish and in excellent condition. No stains as far as I can tell but the photos seem to show some… Got it in Feb/Mar this year in Asia for ~US $150 in a Korean style shop and wore it once or twice since. No material tag (I asked in the shop and was told it has some cotton in it) but I suspect it’s a blend. It has a very nice structure. Lined. The color is true black; not sure what’s happening with the 3rd photo and the rest are representative.
