London Fashion Week and pre-Oscar festivities brought out some seriously hot looks this week, but only one person can be deemed Best Dressed of the Week.
Kate Beckinsale maintained a flawless fashion track record with her off-the-shoulder Vivienne Westwood gown, while another stylish Kate turned heads across the pond in an eclectic look courtesy of Burberry.
Next, Hollywood's two favorite redheads turned on the romance in Elie Saab: Jessica Chastain in a brilliant green lace number and Emma Stone in a white princess-worthy cocktail dress. Eva Longoria, on the other hand, finished out the week in a racy Cushnie et Ochs LBD. The Desperate Housewife wins for overall sexiest, but the most stylish money is on Ms. Beckinsale.
