"On television, Calvin Klein commercials for Essence and Obsession exude an S/M texture, sometimes in color and sometimes in stark black and white, alluding subtly or not so subtly to the sexiness of power. Ads for Guess jeans often portray women adopting an implicitly sadomasochistic pose: as sociologist Ruth Sidel recently elaborated, Guess's magazine copy shows young women either mounting or leaning at the feet of young men who seem to be 'calling the shots'."
