Nomenclature
If a sweater has a zipper that runs from the bottom to the top, it is usually known as a sweatshirt. A hooded sweatshirt is commonly known as a hoodie. A jumper with an open front fastened by buttons or a zipper, is called a cardigan. A hockey sweater was, in the early days of ice hockey, recognisable as what people in the 2000s would call a sweater, but has since evolved into a sort of jersey. Thus, in modern-day North American usage, the shirt of an ice-hockey player's uniform is traditionally called a sweater, regardless of the style.
In British English, a sweater is called a jersey, pullover or jumper, the last two terms being the most common name in British English and Australian English. In South African English, a sweater is always called a jersey. Sleeveless pullovers are known in American English and Australian English as vests or sweater vests. In British English they are known as tank tops or slipovers.
A particularly loud, colorful, or decorative sweater has been known in America the past twenty years as a "Cosby Sweater", being named after comedian Bill Cosby's penchant for wearing them during the run of The Cosby Show.
