A T-shirt or tee shirt, 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.
As slip-on garments without buttons, the earliest T-shirt dates back to sometime between the 1898 Spanish–American War and 1904, when the Cooper Underwear Company ran a magazine ad announcing a new product for bachelors. In the “before” photo, a man averts his eyes from the camera as if embarrassed; he has lost all the buttons on his undershirt and has safety-pinned its flaps together. In the “after” photo, a virile gentleman sports a handlebar mustache, smokes a cigar and wears a “bachelor undershirt” stretchy enough to be pulled over the head. “No safety pins — no buttons — no needle — no thread”, ran the slogan aimed at men with no wives who lacked sewing skills.
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. It became common for sailors and Marines in work parties, the early submarines, and tropical climates to remove their uniform jacket, thus wearing (and soiling) only the undershirt. 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 those reasons, it became the shirt of choice for young boys. Boys’ shirts were made in various colors and patterns. The word T-shirt became part of American English by the 1920s, and appeared in the Merriam-Webster Dictionary.
By 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 was worn by Navy men as undergarments and slowly became common to see veterans wearing their uniform trousers with their T-shirts as casual clothing. The shirts became even more popular in the 1950s after Marlon Brando wore one in A Streetcar Named Desire, finally achieving status as fashionable, stand-alone, outerwear garments. Often boys wore them while doing chores and playing outside, eventually opening up the idea of wearing them as general-purpose casual clothing.
Printed T-shirts were in limited use by 1942 when an Air Corps Gunnery School T-shirt appeared on the cover of Life magazine. In the 1960s, printed T-shirts gained popularity for self-expression as well for advertisements, protests, and souvenirs.
Current versions are available in many different designs and fabrics, and styles include crew-neck and V-neck shirts. T-shirts are among the most worn garments of clothing used today. T-shirts are especially popular with branding for companies or merchandise, as they are inexpensive to make and purchase.
T-shirts were originally worn as undershirts, but are now worn frequently as the only piece of clothing on the top half of the body, other than possibly a brassiere or, rarely, a waistcoat (vest). T-shirts have also become a medium for self-expression and advertising, with any imaginable combination of words, art and photographs on display.
A T-shirt typically extends to the waist. Variants of the T-shirt, such as the V-neck, have been developed. Hip hop fashion calls for tall-T shirts which may extend down to the knees. A similar item is the T-shirt dress or T-dress, a dress-length T-shirt that can be worn without pants. Long T-shirts are also sometimes worn by women as nightgowns. A 1990s trend in women’s clothing involved tight-fitting cropped T-shirt or crop tops short enough to reveal the midriff. Another less popular trend is wearing a short-sleeved T-shirt of a contrasting color over a long-sleeved T-shirt, which is known as layering. T-shirts that are tight to the body are called fitted, tailored or baby doll T-shirts.
With the rise of social media and video sharing sites also came numerous tutorials on DIY T-shirt projects. These videos typically provided instructions on how to modify an old shirt into a new, more fashionable form.
