Shelley modeled part-time during her schooling in the 1960s and started modeling full-time after graduating. She was a very busy model in the 1970s. She was represented by Ford Models Inc. and was one of the most sought after models in their roster. She appeared on magazine covers, spreads and features, commercials and print ads. In 1970, she appeared in an ad for Rovercoat by Arthur Jay. Rovercoat was a fashion line owned by the Arthur Jay Company. Rovercoat specialized in creating women's outer apparel, namely coats and rainwear. The line included clothing, footwear and headgear for women. In the ad, Shelley wore a checkerboard print above-the-knee coat in a textured fabric. It had a leather-look yoke, a leather-look belt, a Peter pan collar and leather-look buttons. It also had matching leather-look gloves. She wore it over a turtleneck sweater top and pants by Happy Legs. Boots by Latinas finished her look. A smart hat accessorized her look. And Shelley looked fashionable and up-to-the-minute.
