Girl With A Funny T-shirt

Named the T-shirt due to the shape of the garment's outline, they soon became popular as a bottom layer of clothing for workers in various industries, including agriculture. The T-shirt was easily fitted, easily cleaned, and inexpensive, and for this reason it became the shirt of choice for young boys (perhaps more the choice of their mothers than of the boys themselves). Boys' shirts were made in various colors and patterns.
By the time of the Great Depression, the T-shirt was often the default garment to be worn when doing farm or ranch chores, as well as other times when modesty called for a torso covering but conditions called for lightweight fabrics.
Following World War II, it became common to see veterans wearing their uniform trousers with their T-shirts as casual clothing, and they became even more popular after Marlon Brando wore one in A Streetcar Named Desire, finally achieving status as fashionable, stand-alone, outer-wear garments.
Beginning in the late 1960s, the T-shirt became a medium for wearable art. Psychedelic art poster designer Warren Dayton pioneered several political, protest, and pop-culture art T-shirts featuring images of Cesar Chavez, political cartoons, and other cultural icons in an article in the Los Angeles Times magazine in late 1969. Today, many notable and memorable T-shirts produced in the 1970s have now become ensconced in pop culture.
