F1 Grid Girls

The official job of a race queen is to hold an umbrella over the driver while his car is being worked on. They generally wear some sort of revealing costume (mini-dress, swimsuit, hot pants, or the like), as well as pantyhose and high heels or knee-high boots. Campaign girls in other countries are generally looked down upon as the occupation is regarded as "low profile" or disgraceful. However, in Japan, race queens have a higher profile and are regarded as idols varying only by the motor sport event they appear in.
The average age for these girls is late teens to early twenties and demand for them wanes with age. Some go on to become models or even actresses but those who are unable to leverage their career into something larger. It is not unusual for some of them to have a background in or a sideline career as an gravure idol. Race queens who operate in prestigious events and with a large fanbase can also be found at automobile shows purely to draw crowds where they are nearly as important an attraction as the cars or electronics products that they are promoting. There is also a magazine dedicated to them called Gals Paradise.
