Shelley began modeling in her teens in 1964. She was discovered by A&P supermarket heir and publisher Huntington Hartford at a debutante ball; and he urged her to try modeling. After consulting with her parents, Shelley decided to give it a go and appeared on the covers and pages many of the top teen magazines of the era. In 1967, she appeared on the pages of the Seventeen Beauty Workshop binder. The mod yellow and pink hardback binder contained tips and tricks for the young women of the time. It contained chapters on Posture, Exercise, Diet, Modeling, Hair Care, Skin Care, Make-up, Grooming, Fashion and Manners. Shelley's pic appeared on the chapter about Modeling. Aside from Shelley, pics of other top teen models of the day appeared on it as well... such as Colleen Corby, Lucy Angle, Regine Jaffery, Terry Reno and Wendy Hill.
