When Donatella Versace throws a party, a star-studded crowd will attend. Case in point: the designer heralded a new era of Versus Versace and debuted JW Anderson's first capsule collection for the brand last night, and to celebrate, Jaime King, Hayden Panettiere, and Heidi Klum dressed up for the occasion. While both Panettiere and Klum selected dresses from Versace's Spring '13 collection, King took the head-to-toe Versus route. And in doing so, the Hart of Dixie star showed off a much more edged-up, safety-pin-included look. Three different plays on evening glamour (with an apropos Versace rocker-girl twist) and only one can be named "best dressed." Vote for your favorite below!
