F1 Grid Girls

Paddock girls are also typically used to advertise the sponsors of their race team. Also known as promotional models, they usually range from 18-30 and are models. They attract attention by wearing tight fitted clothing (often short and revealing) which sport the logo/design of the sponsors.
A promotional model is a person hired to drive consumer demand for a product, service, brand, or concept by directly interacting with potential consumers. A promotional model can be female or male, and typically is intended to be attractive in physical appearance. They serve to provide information about the product or service and make it appealing to consumers. While the length of interaction may be short, the promotional model delivers a live experience that reflects on the product or service he or she is representing.
