Kate, Kelly, and Chloe Wear Black Celebrate Sunglasses at Night

Kate Bosworth sported monochrome black and her new Loewe bag last night to celebrate Ray-Ban's latest collection of Aviators at NYC's Music Hall of Williamsburg. It was Kate's latest fashionable party, and she was joined by a similarly dressed Chloe Sevigny for a short performance by Iggy Pop. Kate stole a moment with Kelly Osbourne, who was in the midst of another fun date night with fiancé Luke Worrall. The sunglasses company always manages to get stylish young stars to turn out for their events, with last year's bringing out the Gossip Girl kids and Diane Kruger to toast their Clubmaster frames.
