Year after year the ball, which raises money for AIDS research, draws fashion's biggest names and best dressed. This year was no exception, with appearances from film stars like Nicole Kidman and style illuminati like Anna Dello Russo. Carine Roitfeld even staged a live fashion show just for the occasion, which amfAR attempted streamed over the web (though sadly, it didn't seem to work). See the evening's best looks.
