A model 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.
Modeling 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 modeling. However, models may be considered to express emotion in their photographs, and many describe themselves as actors. Models are generally not expected to verbally express themselves unless to visually enhance a photograph.
