Heidi Klum attended amfAR Milano 2010 during Milan Fashion Week Spring 2011 at La Permanente on Sept. 27 channeling old world glamour.

She turned heads in a form fitting floor-length beaded Roberto Cavalli gown paired with a retro hair do.

The supermodel has been very busy with other projects including "Project Runway" host, activewear designer, perfume advisor, and mother of 4 children, but that didn't stop her from making an appearance at the event for amfAR the Foundation for AIDS research. The event raised more than $1 million for the charity.

Klum spent the evening mingling with famous faces like fellow Victoria's Secret models Alessandra Ambrosio and Chanel Iman, British singer Leona Lewis, and of course, the Cavallis, whose Spring 2011 show she attended earlier in the day.
