a writeup about Shelley from Vogue, 1979
Shelley was one of the Supermodels of the 1970s. She ranked among a handful of top, top, top models (including Lauren Hutton, Iman, Margaux Hemingway, Karen Graham, Christina Ferrare and Cheryl Tiegs) who were able to negotiate such previously "unheard of" lucrative and exclusive deals with the giant cosmetics companies of the era, and whose names became known to the public. Shelley was known as THE Charlie Girl and was revered around the world. When she became a Charlie's Angel, it was almost an inevitability. It was the natural next step after her success as a Supermodel.
