Given that there were no less than three Costume Institute after-parties—at Mr. Chow, The Box, and Bungalow 8—the lunch Anne Grauso hosted for Olivier Theyskens at BG on Tuesday threatened to be a quiet affair. But there's no slowing down the social set. Champagne hangover or no, Tory Burch, Jennifer Creel, and Marjorie Gubelmann Raein, among others, turned out in their spring best to toast the designer and the arrival of his new Nina Ricci collection at Bergdorf Goodman. Jim Gold, the store's president and CEO, made a vivid speech in which he reminisced about his first Theyskens show eight or so years ago ("it was about 11:30 at night in a smoke-filled fire trap"), but foremost in people's minds were the previous evening's escapades. "Which party did you go to?" Theyskens was asked. "All three," he replied.

The day before, Nordstrom and Vogue hosted an intimate lunch at Keith McNally's new Italian place, Morandi, for a group of Paris-based designers in town for the Poiret gala. After discussion of their outfits, their hair and makeup, and the potential pitfalls of the Met's grand staircases, talk turned to summer holidays. "I was saying we'll all need a vacation after this," commented Giambattista Valli, who would dress Queen Rania of Jordan and Mischa Barton later that night. "Anything that ends in 'os' is nice—Patmos, Skiathos," said Sophia Kokosalaki of her native Greece. "We've always wanted to go," added Azzaro's Vanessa Seward. Perhaps she and her boyfriend, music producer Bertrand Burgalat, are planning a honeymoon? "He told me, 'If I sell 200,000, we'll get married,' " said the designer. "And we're going back to Paris to celebrate his new artist's platinum record."
