A sleeveless shirt, tank top, A-Shirt or Sleeveless T-Shirt is a shirt manufactured without sleeves, or one whose sleeves have been cut off. Sleeveless shirts are worn by either sex, depending on the style. They are often used as undershirts by males, and are often 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. The term "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, it is also known colloquially as a tank top or, disparagingly, as a wife-beater or guinea tee. In the UK an A-shirt, especially when used as an undershirt, is known as a vest.
