Calvin Klein Collection Pre-Fall 2015–The preseason found Calvin Klein Collection women’s creative director Francisco Costa inspired by images of California ease and contemporary American visual artists. With those influences in mind, the pre-fall 2015 outing took on easy silhouettes, patchwork leather, velvet and boucle. The Calvin Klein woman bares her midriff in knitted crop tops while skirts fall to the ground in a straight line. Elsewhere, python boots and “slouchy” clutches complete the effortless look.
