September's New York Fashion Week was, indeed, a marathon—not only due to the sheer volume of collections that debuted on the city's runways, but because the events didn't end with the shows. Fashion Week nightlife is, in many ways, an entirely separate culture with its own fabulous dress codes. Following the days' packed schedule, working models and spectating celebrities alike gathered throughout the city at the evening's most exclusive soirées, wearing outfits that were often far more daring than what you may have seen on the streets during the day.

Celebrities kicked off the week with a bang Friday night at 59th Street Bloomingdale's for Harper’s BAZAAR’s annual ICONS party hosted in partnership with the luxury retailer. Ahead, see additional star-studded nighttime events from the week, and the A-game looks that celebrities were giving. Watch this space for updates, as NYFW continues to run until Wednesday, September 14.
