Inspired by 1920s-1940s French workwear vest. This jacket features a classic indigo-dyed corduroy fabric with narrow stripes, giving it a unique and distinctive look. The varying widths of the velvet stripes add to its special charm. Inside, it's lined with high-density chambray cloth, while the sleeve lining is made of Japanese Bemberg cloth, ensuring comfort and quality. The pure indigo blue hue is vibrant yet not too rigid, and over time, it will develop a beautiful color patina with wear.
