As ever, it’s been a long, long fashion week, and everyone is partied out. Which is why the intimate but festive sit-down dinner thrown by Out of Order magazine and Bulgari, hosted by editor-in-chief Dorian Grinspan and Bulgari’s Stéphane Gerschel and honoring the photographer Ralph Gibson, was just the thing last night. Those who pass freely the worlds of fashion and art — Shayne Oliver, Francisco Costa, Jason Wu, Baz Luhrmann, Klaus Biesenbach, and more — descended into the sunken dining room at the timeless Mr. Chow in uptown Manhattan. Pamela Anderson brought her teenage son Dylan Jagger, too. By the time dinner turned into a riot of dancing atop tables in the wee morning hours, though, Mom was nowhere to be found.
