“Time to show your colors and paint the town with urban chic,” Donna Karan’s show notes declared. The designer was looking at art this season—street art in particular. There were shades of Jean-Michel Basquiat in the scribbled doodle print of a structured bra top and high-waisted pants, and echoes of a certain influential Paris collection (inescapable this week) in the brushstrokes on a V-front dress. In the age of Instagram, everything is up for grabs, available for our repurposing. But in any case, this was one of Karan’s most vital collections in a while: vibrant, uncomplicated, desirable.
