Shelley appeared in many ads during her tenure as a Supermodel in the 1970s. In 1972, she appeared in an ad for the Simplicity Pattern Company, a leading manufacturer of sewing patterns and sewing pattern guides which are distributed throughout the world. They have been manufacturing sewing patterns since 1927 and have allowed fashionistas on a budget and sewing aficionados to create clothes in a reliable manner. The 1972 ad proclaimed that "Now, the prettiest fashions to crochet are also the easiest" and Shelley's image on the package cover of Simplicity pattern 9700 appeared in the ad. Simplicity pattern 9700 contained crochet instructions for making a vest, a pair of hotpants and a skullcap. And Shelley modeled a purple version of the crochet patterns (with pink and green details) and wore them over a white turtleneck top and shorts. Of course, Shelley looked pretty fabulous in all of the pieces.
