This is a beautiful item, worn twice after being purchased as new from Second Street. It's confirmed to be authentic as it received a purchase price when brought to Second Street for resale. I am 170cm tall with a 100cm chest and 88cm waist, and this jacket fits me. It's a slim-fitting jacket, so I think it would be tight if your waist is any larger. This is the Jasper model, sized for Japanese people, and intentionally slimmed down by removing some down filling. If you have an average build, size S should fit. Color: Black Model: JASPER Condition: No stains, tears, or odors.
