In the accompanying article for Carey Mulligan's new W cover, which features her breasts propped up by a fancy Nina Ricci bra, the actress explains her aversion to taking her clothes off for roles:
I’ve never been comfortable with the idea of nudity. I’ve done only seminude, very innocent things in the past, and I’ve always been of the quite British mind-set that I won’t do gratuitous nudity. When it came to this [her new film, Shame], it just seemed so obvious that she [her character, Sissy] is the sort of person who would have no trouble being naked ... She’s an extrovert and wants to be seen. More than anything, she wants someone to acknowledge and help her. I thought I had a week before the nude scene to go to the gym, but we shot it on my first day of filming.
Which actually wound up being fine:
Weirdly, it was fine. You take your clothes off, and you’re like, “Ah — all of you are wearing clothes, and I’m naked, ha, ha, ha.” It’s kind of fun — not that I would continue to do it.
For her W editorial, shot by Michael Thompson, Mulligan got to be fully clothed by Edward Enninful in lots of crisp whites, looking Twiggy-esque with her big black lashes.
