CHANEL HITS SIN CITY: Chanel is hosting a lavish outing this weekend in Las Vegas, flying nearly 200 guests into town on Friday via private jet. Expected VIPs — who will be treated to a first look at Chanel’s opulent “Numéros Privés” installation at the Wynn hotel — include Jessica Alba, Alexa Chung, Jen Brill, Poppy Delevingne, Anouck Lepère, Bee Shaffer, Brad Goreski, Lisa Marie Fernandez and assorted editors. The exhibition encompasses 10 distinct spaces, each dedicated to a specific aspect of Chanel’s history and brand. Rooms include a children’s bedroom with dolls designed by Karl Lagerfeld, a re-creation of Coco Chanel’s iconic apartment at 31 Rue Cambon, a room meant to evoke the interior of a classic Chanel 2.55 handbag and a garden showcasing Chanel’s fine jewelry. Visitors enter via a curtain of white beads, symbolizing Coco Chanel’s favored pearls. “Numéros Privés” will be on view from Jan. 20 to 28, by invitation only.
