The perfect accessory to Zosia Mamet's Golden Globes gown? A new haircut, of course! To accent her embellished black and white number, the Girls star chopped her lengthy strands into a chin-skimming bob. Mamet rarely switches up her trademark layers -- they're essential in creating her character Shoshanna's intricate updos, but she did go solid blonde in January of last year for her role in the off-Broadway play Really Really. "My style beast was awakened when I moved," she told InStyle previously on her ever-changing wardrobe and beauty picks. "There's an unspoken invitation to style freedom in N.Y.C. I never realized how much I like to experiment, and you are welcome to do that here." We're glad to see her experimental tastes have been extended to her hairstyle choices, and if anyone can create a detailed look to flatter her new cut, it's Shoshanna!
