A shirt, also an overshirt or a classic shirt, is a type of clothing related to the outer underwear. Historically, the shirt refers specifically to underwear, but since the 1960s it can be worn on its own.

A sweater or pullover also called a jersey or jumper, is a piece of clothing, typically with long sleeves, made of knitted or crocheted material, that covers the upper part of the body. When sleeveless, the garment is often called a slipover, tank top, or sweater vest.
