AMFAR TO HONOR DUFFY: Robert Duffy, Marc Jacobs International and the singer Fergie will be honored at the amfAR Inspiration Gala on June 7 at the New York Public Library. The event entails an Olympic-themed men’s runway show, and sponsors include MAC Viva Glam, Piaget, Hugo Boss and B&B Italia. “The charity work we do is the most rewarding part of my work, and HIV/AIDS organizations are something I have been involved in for years,” said Duffy, president of Marc Jacobs International. “I feel lucky that Marc has always been so supportive of all the projects I get involved in.” AmfAR’s Inspiration series of benefits in New York, Paris, Los Angeles and São Paulo, Brazil, has raised more than $3 million for the organization since launching in 2010 with producer Josh Wood. The New York gala will be preceded by another São Paulo edition on April 26.
