Fashion Week Parties: Night 5 By Julia Chaplin After a party-filled weekend, the fashion crowd was relieved to spend Monday night at intimate cocktail receptions and dinners. W magazine and Jaeger-LeCoultre feted a new issue devoted to trendsetters called "Generation W." Artists and actors mingled with fashion designers and models at an elegant 1890s mansion off Fifth Avenue. The Dutch model Doutzen Kroes (center) discussed her runway strut. "It's all about the beat," Ms. Kroes said, standing next to a dessert installation by the pastry chef Clarice Lam. I like to walk to house music or something dreamy like the signer Birdy.
