What's IN: "There was an artistically inspired theme across the runways," says Kate Foley, contributing fashion director of Vestiaire Collective. "From Roksanda and Céline to J.W.Anderson, Proenza Schouler, Marni, Valentino, and many other brands, whether directly inspired by a particular artist's work, painterly prints, or patterns, strong art references will be here to stay in 2017." -Rob Cosme
