Calvin Klein underwear is known for its simple-meets-sexy aesthetic, but the latest campaign featuring Lara Stone turned the hotness way up. Shot in black and white by Patrick Demarchelier, Lara looked ultrasultry, wearing Calvin Klein's Naked Glamour collection featuring the brand's signature t-shirt bras and sexier lace pieces. To boot, the slogan states: “Designed to make a woman look even sexier than when naked." While that's up for debate, check out the slideshow to see more of Lara posing in Calvin Klein undies plus images of her for the Fall 2011 campaign.
