As promised, Sienna Miller breezed into Milan Tuesday night to host a Cesare Paciotti party held at the city’s central station. The late-night fete was jam-packed with throngs of fashion types and paparazzi, all trying to get a glimpse of Miller, who was promptly whisked away to a roped-off VIP area upon her arrival. She donned a black vintage dress, Paciotti’s round-toe patent leather Mary Janes and a beaded bag. As for rumors of her potentially posing for a Paciotti ad campaign, she simply replied, “Yes, there are rumors, but it’s not true.” She said her presence was just a friendly gesture to her designer friend. For the woman at the center of so much curiosity — What about Jude? What about Kate? — her pair of Paciottis certainly helped her skip away from any deep questioning.
