Gisele Bündchen, in her role as UN Ambassador, was at the United Nations MDG Summit kickoff party in New York's Museum of Natural History on September 20.
Gisele looked stunning in a form-fitting dress along with nude Louboutin heels.
Her earrings were from Sethi Couture and her ring from Suzanne Kalan.
Also out for a good cause in NYC was Gisele's ex-VS Angel chum Selita Ebanks.
Selita, along with rumoured new beau Kanye West, attended the New Yorkers for Children fall 2010 gala in a metallic Christian Cota gown.
Jewelry brand CIRCA was the sponser of the event, and as Selita was presenter it's probably a good guess that most of her dazzling array of jewels was from them.
