T-shirt
Summary
A T-shirt (also spelled tee shirt), or tee for short, is a style of fabric shirt named after the T shape of its body and sleeves. Traditionally, it has short sleeves and a round neckline, known as a crew neck, which lacks a collar. T-shirts are generally made of a stretchy, light, and inexpensive fabric and are easy to clean. 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.
They are typically made of cotton textile in a stockinette or jersey knit, which has a distinctively pliable texture compared to shirts made of woven cloth. Some modern versions have a body made from a continuously knitted tube, produced on a circular knitting machine, 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.
T-shirts are inexpensive to produce and are often part of fast fashion, leading to outsized sales of T-shirts compared to other attire. For example, two billion T-shirts are sold per year in the United States, or the average person from Sweden buys nine T-shirts a year. Production processes vary but can be environmentally intensive, and include the environmental impact caused by their materials, such as cotton which is both pesticide and water intensive.
Simple, T-shaped top garments have been a part of human clothing since ancient times; garments similar to the T-shirt worn earlier in history are generally called tunics.
The modern 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.In 1913, the U.S. Navy first issued them as undergarments. These were a crew-necked, short-sleeved, white cotton undershirt to be worn under a uniform.
