How appropriate for Gossip Girl’s Leighton Meester to be sitting front row at Jason Wu as the young designer turned out a collection of polished, ladylike looks inspired by a business trip to Japan, where he fell in love with the energy of Tokyo. It came through in saturated color, from a delicate fuchsia knit T to a rainbow of frocks. Known for his eveningwear, Wu did not disappoint, with an array of beautiful, easy gowns that were young and fresh, and sexy sheath dresses with French knots created by hand. Moving his collection forward, Wu ventured into sportswear with cashmere knits, unstructured jackets and shorts all rendered with his sophisticated hand.
