Shelley in an ad for Main Street, 1977
Shelley modeled extensively during the 1970s. When she was a teenager in the '60s, she modeled part-time, during her summer vacations. But when she finished school, she signed on full-time at Ford Models Inc, the modeling agency that represented her, and went on to become one of the highest-paid Supermodels in the world. In 1977, she modeled a Poet's Shirt by Main Street which was 100% cotton and came in saffron-gold, teal, berry red, rust and French blue. And Shelley looked Supermodel sensational in it.
