Color Power - Eva Mendes & Jessica chastain.

Both Eva and Jessica took to their red carpets in colorful Oscar de la Renta dresses.

Eva wore hers to a recent event - the color looked totally delish on her and while most would have chosen to add a belt to the waist to define and give shape, Eva skipped it and worked it just the same.

Jessica wore hers to the photo call of ' The Tree of Life' at the Cannes. She paired her dress with a wide red belt and nude heels.

Delish.
