This is a bankman coat from Great Western Mercantile, a British securities firm, dating from the 1940s-50s. I purchased it at Post Acorn in Osaka. It's apparently a very rare item, and I bought it for just under 200,000 yen. It's a very old item, so there are stains and scratches. I would appreciate your understanding that it is a vintage garment with historical value. Marked size: S (fits like a M) Shoulder width: 45cm Width (underarm): 53cm Sleeve length: 60cm Length: 110cm It has a large fit, so you can wear it casually. I was able to wear thick sweaters and jackets underneath it.
