Alexa Chung, Lady Gaga + More at Versace's Soho Store Launch

When in Rome . . . that seemed to be the motto adopted by Donatella's party guests at her SoHo store opening yesterday. The celebrity party guests, a crowd that included Kanye and Lady Gaga, showed their support for Versace in a range of the label's high-impact wares. Even Alexa Chung, who doesn't exactly strike us as a high-drama Versace girl, embraced the night's theme, albeit tempered with her own charm, in a burgundy leather skirt by Versace's younger line, Versus. Meanwhile, the supermodel contingent, including Coco Rocha and Bar Refaeli, took a page right out of Donatella's book, as did Jennifer Hudson, who joined the leather-clad crew of models in a fit-and-flare skirt and knee-high boots.
