If you haven't heard the name Jessica Chastain, make a note because you will, and soon. The Juilliard-educated actress has seven movies expected to release in 2011, including one where she plays Brad Pitt's wife in the upcoming Tree of Life. Not bad for an unknown, eh? While we can't wait for this promising young thing to hit every big screen, we're already falling for her clean, ladylike style in real life. She sticks to a neutral color palette — all the better to highlight those red locks — and fitted, classic silhouettes that emphasize her gorgeous looks. Check out our fab slideshow of Jessica's best looks so far.
