A Model, is a person in a role either to promote, display, or advertise commercial products (notably fashion clothing) or to serve as a visual aide for people who are creating works of art.
Modelling is considered to be different from other types of public performance, such as an acting, dancing or being a mime artist. The boundary between modelling and performing is, however, not well defined, although such activities as appearing in a film or a play are almost never labelled as modelling.
Types of modelling include Fashion, Glamour, Fitness, Bikini, Fine Art, Body-part and Commercial Print Models. Models are featured in a variety of media formats including books, magazines, films, newspapers, and TV. Fashion models are sometimes featured in films (Looker), reality television shows or music videos.
Celebrities, including actors, singers, sports personalities and reality TV stars, frequently take modelling contracts in addition to their regular work.
