Fashion Police: And the Winners Are Cameron Diaz and Keira Knightley!

Both ladies step out in pale outfits but Cam rocks it like no other while Keira fails miserably

Both stars wore black and tan, but one babe nailed it while the other failed big-time.

Cameron Diaz just barely edged out Blake Lively to take best dressed in our poll last week. She of the tanned stems and toned arms knocked it out of the park in a cute, belted jacket and skirt outfit.

Meanwhile, Keira Knightley's granny-gone-crazy Rodarte dress with black pumps earned her worst dressed. But that's Keira, her outfits are usually either amazing or awful, there isn't much in between. Better luck next time, hon!
