"Red lips are nothing new," Sobol says. "But what makes Emma Watson's look so modern is pairing them with pink cheeks." To get the most natural, just-rolled-around-in-the-hay flush, swirl a pink blush, such as Nars Blush in Gaiety, below the apples, over the center of the cheeks, she says. Paint on a true red lip color with a lip brush—we like Yves Saint Laurent Rouge Pur Couture Pure Colour Satiny Radiance Lipstick SPF 15 in 01. For a long-wearing finish, try Sobol's trick: "Hold a tissue over the lips, tap loose powder over the tissue, and then peel it away. It takes away shine and makes the color last for hours."
