Cannes Style: Rating 9 Dresses

CATE BLANCHETT
For the opening night of the festival — and her movie?s premiere — the Robin Hood star pulled out all the stops in this exquisite Alexander McQueen gown.

HELEN MIRREN
One of our favorite fashionistas wins again with a simply slinky Elie Saab.

KATE BECKINSALE
The Cannes juror?s Marchesa gown could be called ethereal...or just a ton of tulle, which unfortunately overwhelmed the delicately crisscrossed bodice.

SALMA HAYEK
Hayek took Drew Barrymore?s infamous sea urchin gown and did it right in this Gucci dress that cuts down on the crystal quotient and ups the color.

AISHWARYA RAI
With all the volume in her Elie Saab gown and her bouffant, the Bollywood star?s look fell a little flat.

EVA LONGORIA
The Desperate Housewife certainly knows how to bring the drama on the red carpet, as this sweeping Emilio Pucci proves.

EVA LONGORIA
But when it came time for the after-party, Longoria took the opposite route with a short and sleek Elie Saab number.

KATE BECKINSALE
With its draped neckline and dual tones, this demure Dior was the perfect piece for Beckinsale to trot out at the Cannes jury photo call.

CATE BLANCHETT
Blanchett picked an elegant Armani Privé ensemble — with sleeves that flicked at something a little more edgy — for a Robin Hood photo call.
