Shelley modeled for Halston in the '70s and was part of two of the designer's most memorable pictorials. One was the 1972 pictorial for Vogue magazine (which was used as a sort of promo pic for the 2010 Halston film Ultrasuede: In Search of Halston). The other was the 1977 pictorial for Harper's Bazaar. And both were riddled with the supermodels of the era. Women who wore Halston's designs were often referred to a Halstonettes. And sophisticated Shelley was definitely one.
