Denime created the "XX" series - a perfect reproduction of American cotton denim at the time. They are using the "Vintage Banner" denim fabrics made in the 1920s and 1930s to take uncut threads from the denim fabrics.
This jean is based on a 1947 501, one of the most iconic denim cuts. A bit of a higher rise, full top block & seat with a gradual taper.
