LIFE's photographers always had an eye for the provocative and alluring. Sometimes they spotted it on movie sets, where the most beautiful people in the world are hard at work being beautiful. Sometimes it was on fashion runways, where their cameras capture what the young and chic are wearing (or barely wearing). And sometimes, it was just wherever sun and spray prompted revealing displays of well-toned flesh, as in this shot from Co Rentmeester's 1970 photo essay about California beach girls.
