The seasoned actress has not only proven her acting range on the big screen with roles in I Am Sam and Dark Shadows, but also has shown her ability to experiment with different looks in the beauty realm."I was careful not to wear a lot of makeup," she told InStyle in reference to her early day casting sessions. "I'd show up for interviews in men's clothing." Since then, we've spotted the Golden Globe winner decked out in glamorous get-ups, complete with voluminous curls and smoky eyes. And just like fellow thespian and birthday girl Uma Thurman, Pfeiffer is quick to attribute an elevated confidence to aging: "Part of feeling sexy is feeling comfortable in your own skin, and less inhibited, and that goes along with getting older." Hear, hear! In honor of the star's 57th birthday, we're taking a look back at her transformation. Click through our gallery to see her standout red carpet moments.
