The morning after the star-studded soirée, Blasberg took to his highly-followed Instagram account to commemorate the occasion and explained the significance behind YouTube's first-ever channel designed specifically for fashion, beauty and style enthusiasts.

"Last night, we launched YouTube.com/Fashion, the world's largest online home of style video content from around the globe. I was incredibly honored (also: relieved?) so many fabulous fashion folks came out to celebrate," he wrote. "I've always thought mixing fashion and tech was the future... so a special thanks to @future for performing at the party."
