Initially the T -shirt was wron exclusively as an undergarment, but that changed in the 1950s. The fame of the T-shirt skyrockted when actors John Wayne,Marlon Brando, and Jame Dean wore their underwear on the big screen. In 1951,Marlon Brando caused a sensation in his film A streetcar Named Desire when his T-shirt was ripped off his body to reveal his naked chest. Then James Dean made the T-shirt a contemporary symbol of rebellious youth in the movie Rebel without a cause. It became fashionably cool to wear it as an outer garment.
