Reese Witherspoon Jason Wu & Zoe Saldana Giambattista Valli

Last night's annual Children’s Defense Fund's Beat the Odds awards gave the Hollywood crowd a good reason to glam up. The red carpet at the Beverly Hills Hotel drew a chic cast of actresses, styled up to show their support. Alexis Bledel wowed in a fiery-red strapless (incidentally perfect for the Christmas season) — and made us wish we saw the pretty stylesetter out and about more often. Zoe Saldana hit the event in an understated but beautiful plum-hued Giambattista Valli sheath, but it was Reese Witherspoon's post-baby return to the red carpet in a lacy Jason Wu that may be the night's biggest arrival. That, of course, is up to you to decide — click on to see these and the rest of last night's attendees; then be sure to tell us your pick for best dressed in the comments.
