As Greta Gerwig's star continues to rise from indie Mumblecore queen to bona fide Hollywood ingenue, she's showing up more and more on red carpets and in the fashion world. (She attended this year's Met Ball wearing Saint Laurent.) We chatted with her about braving scary red carpets, hiring a stylist, and getting wasted in the ladies' room at the Met Ball. Just try not to want to be best friends with her after reading this interview.
