Shelley in an ad for Qiana by DuPont, 1975
Shelley appeared in many ads during her tenure as a Supermodel. In 1975, she appeared in an ad for Qiana by DuPont. The Qiana look was an easy care look but with the luxury of silk. Qiana was a silk-like nylon fiber that was developed by the DuPont Experimental Station in 1962 and introduced in 1968. It became very popular in the 1970s.
