What makes a model a pin up girl?

There are no height or weight/size requirements to be a pin up girl. A model that specializes in pin up will have a portfolio that showcases this type of work, typically glamour related style that focuses on the model herself and not a product or clothing design. Pin up models are sexy, usually curvy and commonly pose in lingerie, swimsuits, boy shorts, etc. They also wear their hair and makeup in the style of the 1950s or 1960s.

Pin up models create images that fans are able to hang up on their walls. This can include posters, calendars and ads in magazines.
