Shelley in an ad for Sears pants, 1973
Shelley appeared in many ads throughout her modeling career, one of them was for Sears pants in 1973. Dubbed as "Pants That Fit", they were pants that "just refuse to get baggy". They were "trim without being tight". They had "knees that stand up when you do". In fact, you could do anything in them, and they would still looked freshly pressed. They were the perfect pair of pants for the 1970s.
