Last night the Museum of Natural History hosted its annual Museum Dance. The theme of the dinner portion of the evening was the "The Green Environment," and guests were served seared Chilean sea bass amid recycled cardboard centerpieces surrounded by genuine moss and soy candles. Powerhouse designers were represented in full force -- Julia Restoin Roitfeld wore Balmain, Milla Jovovich wore Prada, Jessica Alba wore Narciso Rodriguez, Barbara Bush wore MK & A's The Row and Leigh Lezark wore Chanel. In the beautiful Rose Center, there was dancing till almost dawn.
