Based on 18th century work pants discovered in California. At that time, there were still no belts, and suspenders were essential for dressing up. Also, since belt loops themselves did not exist, people lived with buttons on the waistband and wore suspenders on them. The silhouette is deep in the crotch and thick from the crotch to the hem. The doughnut buttons were extracted from a design of a personal 1910s coverall, and were made of iron without rust-preventive plating. The buckle used for the buckle back is also made from original iron material from the mold. Both the donut button and the buckle back are stamped with the distinctive brand iconic art deco pattern.
