Halle Berry made a striking entrance at the Cannes Film Festival, confidently disregarding the event’s updated dress code. She turned heads on the red carpet, donning a dramatic, billowing gown just before the premiere of the eagerly awaited Mission: Impossible — The Final Reckoning.

The "Monster's Ball" actor revealed exactly which part of her dress made her look ineligible for the red carpet.

Halle Berry revealed that she was going to wear a Gaurav Gupta dress to the Cannes Film Festival opening gala on May 13, but had to switch her dress due to the festival's rule that prohibits dresses with a long train.
