Guests arrived to a busy scene, with fans lined up on 58th Street hoping to get a glimpse of their favorite celebrities arriving. Inside, Belvedere vodka cocktails and Moet & Chandon champagne were served as the glitzy ballroom quickly filled up. Within no time the crowd became a who's who of the fashion and social scene, with high-profile guests in every direction you turned.

Gigi Hadid was as polite as ever, posing for numerous pictures with Devon Windsor. Daria Strokous opted for a dark and alluring look with an inky shade of lipstick and a form-fitting black dress against her porcelain skin, as she met up with artist Harif Guzman at the bar. Lily Aldridge was a jovial as ever in a burgundy velvet pant-suit, and towards the end of the party gleefully photobombed Derek Blasberg before catching up with the man-about-town. She soon met up Candice Swanepoel and Lily Donaldson at a table near the stage, while fellow Victoria's Secret Models Toni Garrn and Constance Jablonski connected again after partying together at Up & Down just the night before.
