Oh, what a night—or make that week—of pretty dresses and parties galore. We spotted Karlie Kloss at Jason Wu‘s VIP table at the Top of the Standard, sharing a hug to celebrate his successful, x-ray-inspired spring collection. “The dress Karlie wore was my favorite,” Wu told us at the post-show fete with La Perla. “It was ethereal, it was tough, and it was beautiful at the same time. It was everything that I wanted to say about the collection.” Click through to see more of Fashion Week’s best parties in the gallery.
