After Shelley graduated from Smith College in 1970, she decided to take on modeling full-time... and began her transition from teen model to top model (and eventually to Supermodel.) Her then boyfriend, photographer Steen Svensson, came up with test shots of Shelley in the hope that the images could get her on the pages of Vogue. Model-and-photographer couples were not uncommon by then. Irving Penn and Lisa Fonssagrives, David Bailey and Jean Shrimpton, Franco Rubartelli and Veruschka were some of the most famous model-and-photographer couples who collaborated often. Shelley and Steen collaborated often as well... for magazine covers, spreads and print ads. In fact, Revlon creative director David Leddick had Steen shoot Shelley's first Revlon Charlie presentation portfolio that got her the contract. And they collaborated on many more Revlon Charlie ads after that.
