The term T-shirt comes from English and means "T-shirt", with the "T" referring to the similarity to the capital letter "T". The comfortable and easy-care men's T-shirt became really popular worldwide thanks to appearances by American actors in successful movies. They appeared in this undershirt in films that were box office hits - especially because of the rebellious and eroticized characters. The men's T-shirt had thus become an icon of pop culture.
