Shelley was a much sought-after model during her modeling days. She appeared in many print ads, including ads for Eagleknit. Eagle Knitting Mills was a manufacturer of knitted headwear (as well as the manufacturer of the original patented earlap cap) and was sold to Zwicker Knitting Mills in 1963. In the 1970s, aside from headwear, Eagleknit came out with caps, hats, shawls and "flings"... all in the latest fashion trends of course. A 1970 ad with Shelley said:
Out there... it's a cold cruel world in the winter. And in that kind of world, a girl has to keep warm somehow. But looking like the abominable snowman doesn't make it. Looking fashionable does. And that's where Eagleknits come in. They're fashionable. They're fun. And they're cozy. Because they're made of super soft, super colorful Creslan acrylic fiber. And if you don't think that's enough to make a girl feel warm all over, just try them. Creslan is a product of the American Cyanamid Co., Wayne, New Jersey.
