Shelley appeared on many ads during her Supermodel tenure. One of them was for Ms. Lee. The Lee Company, a popular American denim jeans brand, came up with a label catering to women. The label catered to the women’s market and was a tribute to women. Ms. Lee was tailor-made for women, in fit and in style. In 1977, Shelley appeared in a Ms. Lee ad with the tagline "The new body stripes from Ms. Lee. Lean, curvy, cleanly sexy... we call them Freeways." It featured cotton denim jeans that had eight lanes of needled-on-color that curved from the waist to the hem, from the front to the back. Shelley wore the Allee denim design with turtleneck top under a shirt. Wedged heels finished her look. A fancy scarf, a beret and a bracelet accessorized her look. She appeared in the ad with model Colleen Corby who wore the Bouleevard denim design with a scoop-necked, long-sleeved top. Heeled espadrilles finished her look. A fancy scarf and a beret accessorized Colleen's look. Both Shelley and Colleen looked stunning in the ad.
