This is a work jacket made from black chambray fabric, likely from the 1920s to 1930s. Based on the lack of inner and outer pockets, it's likely a prisoner jacket. The fabric is a thick black chambray, with a slightly yellowish tint compared to typical black chambray. The collar can be stood up and secured with a hook. The top three buttons are made of a stone-like material, while the bottom two are old plastic buttons. I believe this is a unique piece among prisoner jackets available in the market. 【Size】 Length: 66cm Width: 49cm Shoulder width: 43cm Sleeve length: 57cm *Please note that these are approximate measurements, and some variation may occur. 【Other】 Please only purchase if you understand that this is a vintage item, as it was purchased from a used clothing store.
