The T-shirt has been around since the late 19th century. It was originally made from cotton and had a collar, cuffs, and pocket. In the early 20th century, it became popular as an undershirt for men. During World War II, soldiers wore them under their uniforms. After the war, they were worn by men and women alike. Today, they are still worn by both sexes.
