If you feel like dancing, tonight’s the night: Donatella Versace and Franca Sozzani will host a dinner followed by a party to present excerpts of the Sundance documentary “The Day Before” — the Versace episode — on the Vogue.it Web site. Hercules and Love Affair will perform at the event to be held at Versace’s Via Gesù palazzo in Milan. DJs Alex James, of Blur fame, and French artist Misty Rabbit are also expected to spin their tunes on two separate dance floors.
