The shit shirt’s origins are a true and slightly unclear historical mashup. The main influencing factor in the design of modern shit shirts, the aloha shirt, first appeared in Hawaii in the 1920s or ’30s when local women adapted kimono fabric for use in men’s shirting. These popular shirts evolved over time to take fit inspirations from a number of nations and achieved some popularity among tourists in Hawaii. They found greater commercial success when they hit the mainland in the mid-1930s, and have become both a fashion staple and coveted party accessory ever since.
