Party People: Valentino and Cocktails

This week, Valentino-styled celebs stepped out to honour the label's creative directors, Maria Grazia Chiuri and Pier Paolo Piccioli — and share a few cocktails — in West Hollywood. Chloe Sevigny and Kate Bosworth played hostesses, along with Teen Vogue's Lisa Love, and set the fashion bar high — I'm crushing hard on Kate's red leather pants. True Blood couple Anna Paquin and Stephen Moyer brought their A-game, and Amber Valletta wowed with something leggy. Click on to get the whole Valentino-clad crew.
