A model sometimes called a mannequin, is a person who is employed to display, advertise and promote commercial products (notably fashion clothing) or to serve as a subject of works of art.
Supermodels are highly paid, high profile fashion models. These (usually female) celebrities appear on top fashion magazine covers and in fashion shows. Much more importantly, in financial terms, their appearance in advertising can amount to an endorsement, attracting far greater rewards, especially when they conclude deals to advertise a brand exclusively, as "the face" of that brand.
