In an elegant black cocktail dress, Nicky Hilton sets the bar high for holiday-season dressing. The look is utterly timeless, save for a few fresh updates that make it a standout party style. We love that she pairs her classic strapless LBD with edgier pieces, like a mixed-metal statement necklace, her own jeweled and spiked Nicky Hilton bracelets, and strappy lace-up heels. With a look like this, it'd be easy to take the predictable route, accessorizing with a coordinating clutch, but Nicky's Proenza Schouler pouchette is a much cooler counterpart. Feeling inspired?
