We love that there's an endless amount of ways to dress for a cocktail party — you can either go glamorous, keep it classic, or take a risk. This stylish set proved just that at last night's Antonio Berardi dinner. Emmy Rossum dazzled in a shimmering emerald dress from the designer's Resort 2014 collection, while Nicole Richie showed her edge in a black and cream dress from the Spring 2014 line, which she topped with a fur blazer. She rounded the look out with over-the-knee boots and a metal collar. Meanwhile, Kate Beckinsale showed that the black and white trend is still alive for 2014 in a curve-hugging dress from the Antonio Berardi Resort 2014 collection, accessorized with a metallic clutch and finished with strappy sandals. Which outfit would you rather wear to your next soiree?
