Girls visionary and hipster royal Lena Dunham is officially in the big time. Yep, she's landed the cover of Vogue and a fashion-forward photo spread to match alongside her co-star Adam Driver.

And, if you think she's as uninterested in fashion as her small screen alter ego, Hanna Horvath, it's just not so. "I've always loved Comme des Garçons; I've always loved Yohji Yamamoto.I'm into Charlotte Olympia flats. I really love a Prada bag because they always have one weird detail that you didn't think about. I always wear J Brand jeans because the waist is high . . . a low-cut jean is a problematic thing for me."

Dunham, who's built her career on oversharing, opens up about style, sex and much more in the February issue of the fashion bible, on newsstands Jan. 28.

On the show's unglam portrayals of sex: "There was a sense that I and many women I knew had been led astray by Hollywood and television depictions of sexuality. Seeing somebody who looks like you having sex on television is a less comfortable experience than seeing somebody who looks like nobody you've ever met."

On backlash to her sex scenes with Patrick Wilson: "Critics said, 'That guy wouldn't date that girl!' ... "It's like, 'Have you been out on the street lately?' Everyone dates everyone, for lots of reasons we can't understand. Sexuality isn't a perfect puzzle, like, 'He has a nice nose and she has a nice nose! She's got great breasts and he's got great calves! And so they're going to live happily ever after in a house that was purchased with their modeling money!' It's a complicated thing. I want people ultimately, even if they're disturbed by certain moments, to feel bolstered and normalized by the sex that's on the show."

On being more private than people assume: "I have a really great private existence, almost more like a memoirist or a columnist would, and less like an actor would. ... No one would describe me as a private person, but I actually really am. It's important for me to have a lot of time alone, and to have a lot of time in my house by myself. My entire life sort of takes place between me and my dog, my books, and my boyfriend, and my private world. To me, privacy isn't necessarily equated with secret-keeping. What's private is my relationship with myself."

On whether she can still relate to Hannah's struggles: "I still go to a party andsay something embarrassing to someone, and then write them a weird e-mail about it the next day, and then write them a text because I think they didn't get the e-mail. No matter what happens with your level of success, you still have to deal with all the baggage that is yourself."
