A chemise or shift is a classic smock type of women's undergarment or dress. Historically, a chemise was a simple garment worn next to the skin to protect clothing from sweat and body oils, the precursor to the modern shirts commonly worn in Western nations.

A smock-frock or smock is an outer garment traditionally worn by rural workers, especially shepherds and waggoners. Today, the word smock refers to a loose overgarment worn to protect one's clothing, for instance by a painter.
