Black Pyramid Track Jacket
A T-shirt (or tee shirt, or tee) is a style of unisex fabric shirt, named after the T shape of the body and sleeves. It is normally associated with short sleeves, a round neck line known as a crew neck, with no collar.
Typically made of cotton textile in a jersey knit, it has a distinctively pliable texture compared to shirts made of woven cloth. The majority of modern versions have a body made from a continuously woven tube, on a circular loom, so that the torso has no side seams. The manufacture of T-shirts has become highly automated, and may include fabric cutting by laser or water jet.
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. With and without buttons, they were adopted by miners and stevedores during the late 19th century as a convenient covering for hot environments.
As slip-on garments without buttons, they originally became popular in the United States when they were issued by the U.S. Navy during or following the Spanish–American War of 1898. 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.Y6160237
