Rosario Dawson In Elie Saab - 'As I Lay Dying' Cannes Film Festival Premiere

Rosario Dawson joined Ahna O’Reilly on the red carpet at the Palais des Festivals for the ‘As I Lay Dying’ premiere at Cannes Film Festival this evening, and she was also sporting an on-trend braided updo.

The actress wore an Elie Saab white sleeveless sequinned gown from the Spring 2012 collection featuring a v-neckline and high-slit.

Rosario looks lovely despite the makeshift modifications to the neckline; however, this style of gown has graced the red carpet several times before. In fact, Ahna wore a similar gown just last week.

Also without any definition to the waist, she ends up looking surprisingly boxy.
