Simpsons-Sears was a joint venture between the Simpsons department store chain in Canada and the Sears department store chain in the US. The joint venture began in around 1953. Shelley appeared on many catalogs for Simpsons-Sears in the 1970s. She appeared in several spreads throughout Simpsons-Sears Spring and Summer 1975 catalog. In the spread called "Spring Shirt Tales," she modeled the Big-Value, Big Fashion Print Shirt. The smart short-sleeved shirt had a collar and a front-button opening. It had cuffed sleeves and one pocket. The geometric print she wore was the Navy/Red combo but it also came in a Brown/Yellow combination. Shelley wore it with an equally smart-looking skirt and accessorized it with cool sunglasses and a matching bangle. Shelley looked sensational.
