Model Lisa Jackson channeled Talitha Getty, Stevie Nicks, and Cher when she starred in this issue’s cover shoot, an ode to the 1970s fashions and bohemian style that ruled the runways this spring. Throughout six outfit changes, from barely-there tube tops to stylish denim, she was bedecked in layer upon layer of the season’s sexiest jewels, a mash-up of fine and fashion pieces reflecting an anything-goes ethos.
