Taiga Takahashi spent time researching the history of the sweatshirt and how it went from underwear to an everyday staple of the American wardrobe. Linked to advanced manufacturing processes and the economic boom that enabled this in the wake of World War II, the 1940s saw the sweatshirts become more widely worn as a piece of outerwear. Looking into how these sweatshirts were made, Takahashi found that the technology, a process completed on a loopwheeler machine, was almost obsolete. Only two factories in the world still produce clothing using the loopwheeler machine in Japan and Germany. The sweatshirt is made using the technique in Japan, where Takahashi spoke with the craftspeople about how to represent the sweaters worn in the 1940s more accurately. The result features an organic cotton fleece knit body made using a customised loopwheeler machine. The material is dyed using natural mud and plant dyeing techniques to achieve a unique and beautiful patination.
