Jessica Chastain, who has favored jewel tones this award season since they work with her porcelain skin and fiery red hair, showed up at the 2013 Oscars in a sparkly, blush-colored Armani Prive gown with a sweetheart neckline. It was sweet and curve-hugging and the actress knocked it out of the park, grand slam-style, with this choice.

"I love cinema so much and it is very 'Happy Birthday, Mr. President,'" Chastain told Ryan Seacrest, nodding to the classic gown Marilyn Monroe wore while serenading JFK -- and comparison was perfect. The dress was certainly inspired by Old Hollywood glam and Chastain wore it well.

During the Seacrest chat, Chastain said she is obsessed with fashion, and this dress certainly proves that point.

Chastain's hair fell in soft, side-parted waves. Her lips were painted red, as well, to give her overall look a va-va-va-voom quality.
