Shelley viewed modeling as a business - with the product being herself. Supermodel Shelley said, "As far as (my father) was concerned, I was in business, the business of selling my face." She knew that models had a shelf life; so she would vary her look from time to time. Shelley concluded, "I knew the key was that they always wanted someone new. I decided to hit one market one year, then cut my hair and hit another. Then let it grow and hit television." In 1972, she cut her hair and slightly darkened it to get a more sophisticated look, a more mature look. She went from teen model to young miss and was ready for fashions and styles that would suited young women in the '70s.
