Stana Katic vs. Rachel Weisz in Red Hot Valentino: Who Wore It Best?

Castle star Stana Katic and film actress Rachel Weisz are both beautiful, brunette ladies with amazing figures, but when it comes down to rocking red hot Valentino, who does it best?

Stana wore the cap-sleeved number to BAFTA Los Angeles' 18th Annual Awards Season Tea Party on January 14, 2012. She paired the dress with neutral-colored peep-toe slingbacks by Giuseppe Zanotti and wore her hair down in romantic waves.

Rachel wore the same Resort 2012 Valentino frock to a screening of her film The Whistleblower back in July of last year. Like Stana, the British actress opted for neutral heels and wavy tresses. The only difference is that Rachel's dress seems to have a shorter hemline, while Stana's falls just above the knee for a more demure look.

We think both ladies look fabulous, so we're leaving this one up to you. Who wore Valentino best?
