Some models are employed for their particularly attractive body parts. For example, hand models may be used to promote products held in the hand and nail-related products. They are frequently part of television commercials. Hand model, Ashly Covington has worked on television commercials that are shown around the world. Another hand model, Kimbra Hickey, found fame after being featured on the cover of Twilight.

Modelling (doubled "l" in British spelling, single "l" in American spelling, ) is distinguished from other types of public performance, such as an acting, dancing or mime artist, although the boundary is not well defined. Appearing in a movie or a play is not considered modelling.
