Shelley was THE quintessential Charlie girl and was Revlon Charlie's image model from 1976 to 1982. Charlie was one of the first mega-successful lifestyle brands in the world. The phenomenal success of the brand was due in part to Shelley's unforgettable image. Although there were a slew of other Charlie models before her, it was Shelley's image that catapulted the brand to iconic status. Shelley told Playboy magazine, "Once, on a promotional tour, I was talking with a guy at a radio station and he wanted to know why my Charlie perfume commercials for Revlon were so successful. I suggested we make it the call-in question, because I was curious myself. The women respondents said that this girl walking into a restaurant alone - which most women are afraid to do - looking chic, but not too chic, seemed like somebody they would like to know or to be. I was their idea of a modern, liberated but not threatening woman. The men thought I was someone they would like to go out with; again, modern, not brassy and someone who, if they met me, would talk to them. Men complain about women who can't talk." Shelley's portrayal of the confident, fabulous and independent woman who was unapologetic and happy about that fact captured the imagination of many worldwide and made Charlie one of the best-selling brands in history.
