During New York Fashion Week, the evening events can be just as star-studded as the front rows. This week, there certainly were enough wild parties to keep even the busiest, biggest stars occupied until the early hours of the morning. “I love to party on a normal week,” Charli XCX told W before attending her first Marc Jacobs show, “so fashion week is me on extra-mode.” She wasn’t alone. Over the past few days, headliner stars like Rihanna, Kim Kardashian, Bella Hadid, and many more stayed out way past their bedtimes to hit up some of fashion week’s most exclusive bashes. Here, a look inside some of the most glittery festivities of the week.
