Milan Fashion Week wrapped with last night's black-tie amfAR gala, where some of our Fab favorites turned out, dressed to impress. Black was the color of choice for most, between Alessandra Ambrosio's ladylike strapless, Erin Wasson's vampy black halter Roberto Cavalli, and Chanel Iman's sexy sheer number. As for the rest, Heidi Klum chose a jeweled Cavalli, and Margherita Missoni stepped out in a patchwork metallic creation. Click through to see them all, then cast your vote for the most Fab!
