Shelley appeared on many Simplicity pattern catalogs, brochures and packaging during the 1960s and 1970s. The Simplicity Pattern Company is the 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. Shelley appeared in Simplicity Young Ideas Catalog's Fall-Winter 1972 issue.
In the issue, Shelley appeared in the spread called "The Craft Craze... Work It Out." It featured patterns for fashion accessories that readers could crochet themselves and add to their present wardrobe. Shelley wore pieces from Simplicity pattern number 5228. It contained step-by-step crochet instructions for a beret, a scarf, a tie, and a turtleneck dickey - accessories for the fashionista in the early '70s. The beret had a ribbed band and an optional pom-pom. The scarf was 6 feet long and had a fringe trim. The tie could be made in a solid color or with stripes. The dickey had a ribbed turtleneck. Shelley wore a version of all the patterns and looked fab in all of them.
