A sweater (American English) is a knitted garment intended to cover the torso and arms; either a pullover or a cardigan, distinguished in that cardigans open at the front while pullovers do not. In British English, a pullover may also be called a jumper or jersey. (...) Sweaters are worn by adults and children of both sexes; often over a shirt, blouse, T-shirt, or other top, but sometimes next to the skin. Sweaters were traditionally made from wool, but can now be made of cotton, synthetic fibers, or any combination thereof. (...).
