Nominated for: Her outstanding performance in a lead role in Mad Men.
Why we love her: We've followed her onscreen struggle up the corporate ladder as Peggy — and rooted for her every step of the way. And it's just as fun to watch her transformation on the red carpet; out of her retro costumes, Elisabeth steps into some pretty serious fashion. She's playful — with a penchant for showing her stems. Case in point: this statement-printed Clover Canyon sheath she wore for an appearance in NYC this year.
