Congratulations! Félicitations! Congratulazioni! Mazel Tov! You've made it through FNO, and you're not even (that) hungover! Or at least you're semi-functional at work. To celebrate, we've put together an instant flashback of all the "I can't believe that happened" fun from the big night out. The Mayor hung with DVF, Aziz Anzari stopped by to hear Jessie Marco DJ at GQ, and there's not one drop of champagne left in NYC. Wait, that could be a serious problem. Click through to check out all of the dancing, the drinking, the slashed price-tags, and of course — the incredible fashion that inspired it all.
