Transformation

As Peggy Olson on Mad Men, Elisabeth Moss has endured a series of not-so-flattering coifs meant to convey the character's all-business nature. In her own life, the actress knows how to flatter her porcelain skin and bright blue eyes, switching between blond and brunet locks with equal success. "I like that I get to go back and forth," Moss once told InStyle. "I feel invigorated style-wise when I change hair color."
