Yes, Dupont, the company that brings you "Better things for better living...through chemistry" took out a multi-page advertisement in the spring of 1969 featuring it's Orlon acrylic blend fabrics used by Paris couturiers.
The 1960s were known for technological advances and the use of synthetic materials in avante-garde fashion. We saw the use of vinyl, mylar, and other synthetics. By the late 60s, the traditional couture client was becoming a thing of the past. Ready-to-wear was experiencing an explosion of popularity. Dupont seized upon the opportunity to promote it's man-made fibers to the couturiers and to benefit from the status that link provided. And, no doubt, money exchanged hands as part of the deal.
