The latest scenester bar of choice, Double Seven, nestled in the Meatpacking District, is playing host to a slew of Euro-fabulous parties during fashion week. On Sunday night, Luella Bartley and stylist Katie Grand are having cocktails for their nearest and dearest after Bartley’s fashion show that day. Padma Lakshmi is celebrating her 32nd birthday Tuesday, she says. The guest list is unconfirmed, but hubby Salman Rushdie certainly will be by her side. Thursday night, another model-cum-writer, Sophie Dahl, will take over the space to ring in her 27th birthday. Dahl’s pals — who include a bevy of models and/or Brit hipsters such as Jacquetta Wheeler, Alexi Lubomirski, Karen Elson, Natalia Vodianova, Justin Portman, Erin O’Connor, Alice Temperley, Bay Garnett, Jefferson Hack and Tabitha Simmons — will get to sample a specialty cocktail the bar is making especially for Dahl called “The Duchess” — one of the willowy blonde’s nicknames.
