<human>: I want to know more about the history of the tee shirt?
<bot>: The T-shirt is believed to have been invented in the early 1900s by a company called the American Cotton Shirt Company. It was originally made from cotton fabric and had a collar and buttons. In the 1920s, it became popular for men to wear shirts without collars and with short sleeves. By the 1950s, the T-shirt had become an iconic symbol of youth culture, especially among teenagers. Today, the T-shirt has evolved into many different styles and fabrics, including cotton, polyester, spandex, and bamboo.
