Shelley first became famous in the 1970s as THE Charlie Girl. In 1976, she was hand-picked to represent the Revlon Charlie brand, as she was the embodiment the brand's ideal – gorgeous, sexy and young. Makeup artist Rick Gillette recalls, "Shelley Hack was really the perfect girl for Charlie. I remember when Revlon creative director David Leddick had Steen Svensson shoot the first presentation with her that got her the contract." They shot a commercial with her and when it debuted, it was an immediate and immense hit. By 1977, Charlie became the #1 fragrance in the world (the first American-made international bestseller). In 1977, she appeared in a newspaper ad for Charlie called the "Make It A Christmas To Remember With Charlie From Revlon." It was a promo for the "Charlie Fragrance Coup" which contained a bottle of Charlie perfume spray, Charlie Body Silk, Charlie Body Silk Foam Bath, Charlie Body Silk and Charlie Bath Soap. It was worth just $4.75 with any Charlie collection purchase. Now wasn't that a fabulous Christmas gift to receive? Shelley, as always, was gorgeous in the ad.
