A model is a person with a role either to promote, display or advertise commercial products (notably fashion clothing in fashion shows), or to serve as a visual aid for people who are creating works of art or to pose for photography. It helps to have both an online version (your modeling portfolio website) that you can send to anyone via an email and a printed version that you can show when you meet someone face to face. You need all the exposure you can get to move up the ladder in the modeling industry.
