Teeshirt

A T-shirt (or t shirt, or tee) is a style of unisex fabric shirt named after the T shape of its body and sleeves. It normally has short sleeves and a round neckline, known as a crew neck, which lacks a collar. T-shirts are generally made of a light, inexpensive fabric and are easy to clean.

Typically made of cotton textile in a stockinette or jersey knit, it has a distinctively pliable texture compared to shirts made of woven cloth. Most modern versions have a body made from a continuously woven tube, produced on a circular loom, such that the torso has no side seams. The manufacture of T-shirts has become highly automated and may include cutting fabric with a laser or a water jet.

The T-shirt evolved from undergarments used in the 19th century and, in the mid-20th century, transitioned from undergarment to general-use casual clothing.

A V-neck T-shirt has a V-shaped neckline, as opposed to the round neckline of the more common crew neck shirt (also called a U-neck). V-necks were introduced so that the neckline of the shirt does not show when worn beneath an outer shirt, as would that of a crew neck shirt.

The T-shirt evolved from undergarments used in the 19th century. First, the one-piece union suit underwear was cut 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, the earliest T-shirt dates back to sometime between the 1898 Spanish–American War and 1913, when the U.S. Navy began issuing them as undergarments. 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.
