Jessica Chastain's Givency Dress Is Simply Grape-tastic

Zero Dark Thirty 's leading lady shines bright like a...grape this sequined stunner

Sometimes all a forgotten shade needs is a little attention from a major leading lady.

Jessica Chastain revived the color purple when she hit the carpet at Cannes in this attention-grabbing violet Givenchy by Riccardo Tisci gown. Purple is back, bitches!

Sure, the shade sort of reminds us of a giant bottle of Dimetapp cough syrup. Or what Violet Beauregarde might wear to senior prom. But that doesn't diminish the gorgeous features of this dress.

We love the simple, sexy neckline and that tasteful slit up the front. Plus, those shiny embellishments certainly draw attention to all of Jessica's curves.

So is purple the new black? Somebody notify Vogue!
