In a stunning strapless Jason Wu dress, Reese Witherspoon makes compassion look ever so fashionable. Always willing to lend her star power for a great cause, the Sweet Home Alabama actress wore Jason Wu’s dress to An Unforgettable Evening Benefiting Entertainment Industry Foundation’s (EIF) Women’s Cancer Research Fund last night in Beverly Hills.

The dress, from Jason Wu’s Pre-Fall 2010 collection, boasts exquisite and delightfully feminine lace detailing along the hem and bodice. Its purposefully-placed black satin belt and elegant draping create a demure, ladylike silhouette.

Reese Witherspoon’s chic peeptoe pumps and sleek locks were the perfect compliments to her fabulous dress. A beauty on the red carpet, Witherspoon attended the fete alongside several celebrities, including Taylor Swift and Olivia Wilde.
