Just when we thought we couldn't be more impressed (or in love) with Freida Pinto's pink Michael Angel perfection and Eva Longoria's gauzy Marchesa gown at the Cannes Film Festival opening ceremony, the dazzling duo pulled an outfit-change fast one on us. For the ceremony dinner, both had slipped into something much darker, slinkier, and altogether sexier. Freida chose a striking black sequin Versace number with a sheer neckline, sheer sleeves, and a thigh-high slit, while Eva channeled her sultry side in a black Alberta Ferretti gown, complete with body-con nude slip, lace piping, and delicate tulle overlay. It really comes down to a stylish battle of the ultrafeminine dresses vs. the more gothic gowns — and we want to know which set of looks you like best. Time to weigh in: are you partial to Eva and Freida's girlier red-carpet picks or their darker dinnertime wares?
