The Help star poses half naked in a floor-length, peach-coloured dress rolled down to the waist for the Vanity Fair spread, which was shot by top photographer Mario Testino.
A strategically-placed left arm preserves her modesty.
The actress admits the revealing shoot was a big step for her because she has spent her lifetime riddled with feelings of insecurity about her body image.
She tells the publication, ""I've spent my life being embarrassed. I don't want people to look at me.""
