Hot on the heels of Fashion Month, some of the style set's most social members have been spotted on both coasts. After partying with Salvatore Ferragamo in San Francisco earlier this week and gathering to honor the nominees for the CFDA Awards in New York, some of our favorite designers were at Bloomingdales to debut a new project for the department store called The Collective.
But perhaps the most stunning outfits came courtesy of the Young Fellows Ball, which attracted the likes of Chloe Perrin and the ever-stylish Hannah Bronfman. We're taking a look at the most exclusive parties to host fashion's biggest names, here in the gallery.
