Girl With A Funny T-shirt

History
The T-shirt evolved from undergarments used in the 19th century, through cutting the one-piece "union suit" underwear into separate top and bottom garments, with the top long enough to tuck under the waistband of the bottoms. T-shirts, with and without buttons, were adopted by miners and stevedores during the late 19th century as a convenient covering for hot environments.
T-shirts, as a slip-on garment without buttons, originally became popular in the United States when they were issued by the U.S. Navy during or following the Spanish American War. These were a crew-necked, short-sleeved, white cotton undershirt to be worn under a uniform. It became common for sailors and Marines in work parties, the early submarines, and tropical climates to remove their uniform "jacket", wearing (and soiling) only the undershirt. It is possible that the Navy uniform boards first discovered the T-shirt by watching dock crews.
