With outrageous Halloween costumes finally behind them and a fresh month ahead (all eyes on Thanksgiving), the glittering mob of celebrities, fashion designers, models, and socialites showed their impeccably made-up faces at only the finest events. Chloé hosted its first-ever fashion show in Los Angeles, luring in what seemed to be all of Mad Men's leading ladies (Jessica Paré, January Jones, Kiernan Shipka, Elisabeth Moss). In the same city, Lana Del Rey posed with Moschino's new creative director, Jeremy Scott, at the Nylon and Wildfox Party. Back east, everyone from Elettra Wiedemann, Coco Rocha, and Alec Baldwin gussied up to attend the Artwalk NY Benefit. And Pharrell, Swizz Beatz, and Alicia Keys brought their collective cool to Emmanuel Perrotin's latest gallery opening, KAWS: Pass the Blame.
