This is a French vintage workwear piece, also known as an atelier coat or shop coat. It's made of black chambray, a fabric often referred to as "goma-shio" (sesame salt) and is representative of French workwear. It's also known as "black chan." It has a "GALERIES LAFAYETTE-Galstar-" tag. The name of the department store "GALERIES LAFAYETTE" which has its main store in Paris, is attached, and it was ordered as a special order from the manufacturer "Galstar." The precision and care of the sewing, as well as details like the sleeve straps, are remarkable.
