T.T coverall jacket is modeled after an American workwear piece from around 1910. During the mass-production era of the 1920s, garments were valued more for durability than design—functionality took precedence with linear sewing, flat patterns, and hardwearing construction. These pieces were closer to tools than clothing. While retaining the original specifications, this version has been restructured with sloped shoulders to reduce bulk under the arms. The fabric is a high-density back satin woven from cotton and linen. Hemp yarn is used in the weft to bring the natural coolness of linen, while open-end spun cotton yarn is used in the warp to create a supple, textured finish. The buttons and backside parts marked with original engravings are all made of iron. BEIGE uses uncoated iron to allow rust to form over time, embracing the beauty of natural aging. BROWN and CHARCOAL feature a smoked-like plating finish, expressing the passage of time in a different way.
