Young Blonde Girl Wearing Long Sleeved Sweater On The Deckchair

One advantage of sweaters is that they conform well to the body without requiring the tailoring as woven garments. For example, shaping such as darts, flares and gores — commonly found in woven blouses, a comparable garment — are rarely needed in sweaters, thanks to the Elasticity and drape of knitted fabrics. Even when such shaping is needed, it can be knit into the fabric itself, without requiring seams. However, this very elasticity makes it necessary to use more care when washing.
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.
