Last evening, over 500 of New York's most stylish aesthetes, philanthropists, and scene staples flocked to the Park Avenue Armory to celebrate The Winter Show's annual Young Collectors Night benefit for East Side House, presented in partnership with Cara Cara.

Snaking their way throughout the show, which featured a truly divine curation of jewelry, furniture, art and more, the crowd came dressed in their 'Jet Set Formal' best. 

Curious what the heck that dress code actually means?
