sleeveless shirt introduction
A sleeveless shirt is a shirt manufactured without sleeves, or whose sleeves have been cut off. Sleeveless shirts are worn by people of any gender, depending on the style. They are used as undershirts, or worn by athletes in sports such as track and field and triathlon, and are regarded as acceptable public casual dress in most warm-weather locales. (multi-pocket-vest)
A-shirt is short for "athletic shirt" because it is often worn in sports, such as basketball and track-and-field events. In the United States and Canada, it is commonly known as a tank top and also by the pejorative nicknames wifebeater, guinea tee, or dago tee ("guinea" and "dago" being American ethnic slurs for people of Italian ethnicity). In the UK, an A-shirt, especially when used as an undershirt, is known as a vest (compare the American usage of "vest"). Another term is singlet, used in England, Scotland, Ireland, Australia, Ghana, Nigeria, Hong Kong, Singapore and New Zealand. In the Philippines, when used as an undershirt it is called a sando. In Bangladesh and the State of West Bengal in India, (combat-vest)it is called a sando-genji; in other eastern states of India it is called sando-ganji. In India it is known as a banian and is used extensively as an undershirt to absorb sweat and prevent its penetration to outer layers of clothing. In France, it is commonly called a marcel after Marcel Eisenberg, who first started large-scale production of the shirts for Parisian porters during the mid-19th century, or more formally a débardeur, meaning "docker", "porter" or "stevedore".
In addition to athletic usage, A-shirts have traditionally been used as undershirts, especially with suits and dress shirts. They are sometimes worn alone without a dress shirt or top shirt during very warm and/or humid weather, mainly in North America where the climate is warmer and more humid in the summer. A-shirts are often worn alone under very casual settings, as lounge wear, and/or while completing yard work or other chores around the home.
The build of an A-shirt is simple: the neck and armholes are often reinforced for durability. One usually has large armholes and neck holes and a neckline that can reach down as far as the bottom of the chest. (Women's A-shirts have smaller holes, to conceal their breasts). They are also sometimes made long to make tucking into a pair of jeans/shorts easier. In almost all cases, they are buttonless, collarless, and pocketless. An A-shirt worn as an undershirt is designed for a tight fit and is often made of ribbed cotton.(fleece-vest)
A tank top consists of a sleeveless shirt with low neck and different shoulder straps width. It is named after tank suits, one-piece bathing suits of the 1920s worn in tanks or swimming pools. The upper garment is worn commonly by both men and women.
