Shelley in a pic for Seventeen magazine, 1965
Shelley began modeling in late 1964. Her first covers for Glamour and Seventeen magazines came out simultaneously in November of 1964. In October of 1965, just almost a year after her first covers, she appeared on the pages of Seventeen magazine. In the spread called "Sew Up New Love-Notes Lace," she modeled a dress in the color of every girl's best note paper and made from the prettiest, most romantic lace designs. The dress was a tailored shirtwaist in ecru lace with a spider-web pattern. It had a neatly turned collar and long ruffled sleeves. It was McCall's pattern no. 8047. Shelley looked young and stylish.
