Shelley began modeling in her teens and was represented by Eileen Ford. Mrs. Ford was an acquaintance of her mother's - who was a former model herself. Shelley said, "Modeling was a great summer job. It beat waitressing." Modeling remained a sideline however, as Shelley concentrated on her studies. But after graduating college, she signed on full-time at Ford Models Inc. and became one of the highest-paid models in the business... a certified Supermodel. She appeared in numerous commercials, tons of print ads and various magazine spreads. On October 1976, she appeared on the pages of Harper's Bazaar, in a spread called "The 6-Piece Wardrobe for Evening". It featured fashion pieces from the Fragments by Harriet Selwyn collection in chiffon and jersey. Each could be mixed and matched for any or every night of the week. The pieces consisted of a short-sleeved surplice top, a long soft skirt, a long-sleeved surplice top, a peasant blouse, a pair of jersey pants and a sheer-and-sexy chiffon blouse... in tones from deep gray to the palest of peach. Jewelry by Prado Designs finished her look. And Shelley was just Supermodel fabulous in the spread.
