There's nothing new under the sun.I had a girlfriend in the early eighties who was a dancer, she had what I used to call a Mohican but we now know as a Brazilian, she told me at the time that several of the girls she knew shaved it all off. This was because of the high legged costumes they wore and quick costume changes, to avoid any hint of pubic hair being shown. In those days it was a real novelty to me but I understand that some dancers in the fifties used to trim or shave, the romans apparently used to shave or pluck all body hair,
