Young College Girl Wearing Sport Jersey

A jersey is an item of knitted clothing, traditionally in wool or cotton, with sleeves, worn as a pullover, as it does not open at the front, unlike a cardigan. It is usually close-fitting and machine knitted in contrast to a guernsey that is more often hand knit with a thicker yarn. The word is usually used interchangeably with sweater and is the name always officially used in the United Kingdom to refer to the item when worn as part of the uniform of military, police or other uniformed personnel.
