The 'ny' in nylon is from the words New York. When Du Pont decided to develop nylon into a commercial fiber, the company specifically intended to use it to compete with silk in the women's hosiery market. The choice was deliberate, strategic, and significant. Years of research devoted to targeting this particular market proved enormously successful. Seamed sheer nylon reinforced stockings were the rage because of affordability durability and the shiny look.
Nylons are a luxury item that provokes a mysterious sensuality to both females and males alike.
That bare leg look gives a serious peek at Taboo female soft creamy alluring sensual skin. An old Victorian taboo that still evokes male starry-eyed glazes, males are perceived as sick perverts if caught staring at legs in public. It's similar to prohibition and makes the object even more desirable and mysterious. So photographs of nylonically clad legs are desirable so that the mysterious taboo can be observed in private for the pleasure not allowed in public. The sexual allure of creamy female perfumed skin shaded by the sensual semi-transparent thin fabric of sheer nylon provokes the mystery all the more to both females and males the world over.
