Shelley's smile was one of the most famous and most unforgettable smiles of the '70s; and it was made even more famous by her Charlie perfume commercials and print ads. Her modeling clients "like me to look happy" Shelley told Cosmopolitan magazine in 1974. "My smile is crooked," she added, "there's is really very little I can do about my smile except control the upper left side without looking stiff." Well,crooked or not, Shelley's smile was and is unforgettable.
