Earlier today in Milan, the Spice Girls made a surprise appearance on the Roberto Cavalli catwalk. The Fall 2008 men's runway shows are in full swing, and the girls came to show their support for the man who painstakingly designed their world tour costumes. As Cavalli revealed about his efforts, "I met each one on their own so I could get an idea of their personality." The runway show's dress code was all black, with the exception of Geri Halliwell, but unsurprisingly, Posh stole the show with a plunging tuxedo pantsuit. Which spicey look here is your fave?
