Diane Kruger may not be the first Hollywood actress to claim she's low-maintenance, but she may be the most honest. It's an unlikely trait for someone who's one of Karl Lagerfeld's muses (they're neighbors in Paris) and thinks people believe she wears only gowns (the slideshow will attest to this). But the 34-year-old doesn't have a stylist and almost always does her own hair and makeup (unless it's the Oscars). Kruger, whose thriller Unknown comes out next month, is actually fairly critical of her own technique. Looking at one picture of herself, she deemed the hair "medium good," while the makeup was "pretty good." The outfit, however, she loved. "If you have a beautiful dress," she says, "that's enough—you don't need much else." Her faith in all things fashion extends to her roles—she tends to embrace the aesthetic of her characters. After Inglourious Basterds, she had a thing for red lipstick. "I used to look for dresses I could specifically wear with red lips," she admits. Meanwhile, in Unknown, in which she stars opposite Liam Neeson, she plays a tough Bosnian girl who loves Doc Martens and ear piercings. "I actually just had my ear pierced, and it still kind of hurts," she says. "I love it—but my mom was not so pleased." For better or worse, her most daring fashion moments still resonate with her: "I look back at pictures of myself from 10 years ago and go, ‘What was I thinking?' "
