Eyes were misty after a Cinema Society screening of “Snow Flower and the Secret Fan” on Wednes day night. The film, based on the best seller about two generations of inseparable female friends, had guests including Donna Karan and Nicole Kidman weeping. Ivanka Trump told friends at Diane von Furstenberg‘s studio for a Mr. Chow-catered supper that it was her last appearance before giving birth. The fete also drew Mayor Bloomberg, Anna Wintour, Lucy Liu, Irina Shayk, Harvey Weinstein and the film’s producer, Wendi Murdoch.
