<human>: I want to know more about the history of the tee shirt?
<bot>: The first known use of a T-shirt was in 1589, when it was worn by French soldiers. It is believed that the name "T-shirt" originated from the French word for a small round shield. In the late 19th century, the cotton T-shirt became popular with workers and athletes. By the 1930s, the T-shirt had become an integral part of American culture, as well as being adopted around the world. Today, T-shirts are worn for many different reasons - from sports teams to casual wear.
