And the recent movement to full-scale hair removal below the neckline is an entirely modern phenomena that may have its roots in the popularity and availability of pornography. Once upon a time, a Brazilian wax would have been the height of scandal. And even twenty years ago, a shaved you-know-what would have been a rarity if you weren’t in the Industry. But increased visibility of lady parts on-screen has led to changing fads in landscaping everything down below. Like Clara Bow’s eyebrows, we all just can’t help imitating the things we’re seeing in the movies, even if those films are far from PG.
