Claire McCardell, 1949

Claire McCardell was well known for her easy-to-wear sportswear designs.  In the spring of 1949, her designs were featured in this 2-page ad for fabric manufacturer Celanese.  Celanese had developed a new acetate/rayon sharkskin fabric that was knit rather than woven.  Sharkskin is normally associated with men's suits from the late 50s and early 60s.  It has a smooth finish with a subtle shiny finish.  This fabric would have been perfect for McCardell's esthetic, as it was comfortable and wrinkle resistant.
