Mario Testino’s Grand Exhibition Launch

While Los Angeles is in the midst of Oscar fever, Milan is all about the runways. And at night, it’s all about boogying down. Yesterday evening at the Palazzo Serbelloni, the fashion flock converged for a party hosted by Franca Sozzani and Abdul Aziz al Rabban for one of the industry’s favorite shutterbugs, Mario Testino. Among those toasting the gregarious photographer’s latest project, “An Issue,” were Vogue Editor-in-Chief Anna Wintour, designers Alberta Ferretti and Jeremy Scott, and bright young things including Bianca and Coco Brandolini d’Adda, who all enjoyed the grand setting and a performance from Rita Ora. But the best part of the evening? When Anna Dello Russo took to the microphone for an impromptu set.
