In the United States in the 1920s, there is a sweatshirt jacket called a sweat coat. It has buttons made of Bakelite, a material commonly used in industrial products before the invention of plastic, and is made of various different materials, including the collar and front construction, cuff ribs made of circular knitting, and waist ribs. Despite its simple appearance, it is quite complicated, and I extracted as much as possible with the materials and sewing that made it complicated. I also added my own reinterpretation and created a garment that is completely different from the original sweat coat. 100% COTTON
