Nicky knows how to dress for Vegas impress. She and her man, David Katzenberg, hosted a party at Hard Rock's Vanity Nightclub over the weekend, and Nicky wore Phillip Lim's sequined shirtdress. No doubt it's super sparky, but the menswear cut keeps it classy. Evening shirtdresses are available in all-over adorned as well as subtle shimmer. You can load on the ice, too, like Nicky, for added drama.
