A model (from Middle French modèle), sometimes called a mannequin, is a person who is employed for the purpose of displaying and promoting fashion clothing or other products and for advertising or promotional purposes or who poses for works of art. Modelling ("modelling" with a doubled "l" is British spelling, vs "modeling" single "l" 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.
