There were mixed results, but the majority of you loved Katy Perry in this Matthew Williamson for H&M dress. Does the dress suit heiress Nicky Hilton, too? She wore it hosting a party at Prive Las Vegas. She opted for an oversized clutch, keeping with the feather theme, while Katy wore a cheeky pink metallic lip clutch. As well, Nicky went bare legs and matchy shoes, while Katy wore tights and metallic shoes. Who wore this peacock frock best?
