This is a men's stand-collar coat by Hiroko Koshino. The color is a dark navy that is almost black, mixed with charcoal gray. It's a chambray fabric with a glossy and crisp feel. I think it can be worn in a business setting. It's a size LL, so I think it can be worn comfortably over a suit. The coat's actual measurements are all approximately in cm: Width: 60 Length: 90 Shoulder width: 50 Sleeve length: 64 Collar width: 6-8 Vent length: 33 Please feel free to ask any questions.
