Bikini car washes are a summer event that occurs possibly as a fund raiser for a school, a sport association or another youth organization or charity. Typically, females in bikinis bring in donors by standing on a roadside with colorful cardboard signs or posters, and the cars are washed by their classmates in a nearby parking lot. Depending on the organization responsible, as well as the local laws, a variation of the bikini car wash sometimes occurs, in which the girls will wash the car topless, usually for an extra fee. This type of car wash is not found in the US as part of any legitimate charitable or fund raising event. There are also commercial bikini car washes, where bikini-clad girls actually wash the cars for a fee and the entertainment of the drivers. Hooters restaurants usually have bikini car washes in the summer to attract customers.
