Sweater vest

A sweater vest, also known as a sleeveless sweater and tank top or sleeveless jumper (UK), is an item of knitwear that is similar to a sweater, but without sleeves. They were popular in the 20th century, particularly in the 1970s in the UK, and are again growing in popularity in this century.

The name "tank top", recorded in English since 1968, derives from its resemblance to a tank suit, a style of one-piece women's swimsuit with shoulder straps, so called since the 1920s, because it was worn in a "swimming tank", an obsolete term for a swimming pool. In American English, a tank top refers to a sleeveless shirt (what in British English would usually be called a vest).

Styles

One of the most common patterns on a sleeveless sweater is argyle. Many newer designs feature a return to popular patterns from eras past. Other variations include designs of a more modern nature, including stripes. Some of the most common of neckline shapes are the V-neck and the crew neck, which is similar to a common T-shirt neckline.
