On the final day of New York Fashion Week, Calvin Klein Collection Women’s Creative Director Francisco Costa continued his sleek and modern vision for the label’s fall-winter 2015 collection. The outing was nostalgic with shades of 1960s mod and 1970s sex appeal, but still had a contemporary feel thanks to rich fabrications like manipulated leather and wool with patchwork and frayed details. The color palette was subtle with an occasional lacquered red or blush pink hue. Footwear embraced a short, blocky heel that was popularized in the 70s.
