Work by WHITE STAG, a famous sportswear brand such as ski wear. Wear-type coveralls, although there aren't too many of them at WHITE STAG workwear. You can sometimes find them in thrift stores, too. The one introduced here is for women, since it is on the left front, but men can also wear it in feeling. The texture of the denim feels like it's from the 1940s and 50s, but the date of manufacture is a material for identification. Scant and unspecified.
