It happens to all of us, but as Jennifer Lawrence found to her cost at the Screen Actors Guild only celebrities have a camera pointing at them when their wardrobes malfunction. And the award for best wardrobe malfunction goes to... Jennifer Lawrence, the 22-year-old star of Silver Linings Playbook, whose flowing gown appeared to turn into little more than a basque as she stepped up on stage to receive her award for Best Actress at the Screen Actors Guild ceremony on Sunday night. Marion Cotillard gasped. Nicole Kidman sneered, in much the way that a woman who hasn't had a hit movie for years might when confronted with the sight of a younger model coming undone during her moment of glory. Aha. HA," her suspiciously smooth face seemed to want to say. IN PICTURES: SAG Awards fashion hits and misses Sadly, video did not record the reaction of Robert De Niro, who was presenting the award. One imagines he was probably thinking something along the lines of "Wahey!," as the bottom of Lawrence's frock slipped further away from its top, revealing a good four inches of thigh. Had someone - anyone? Nicole Kidman? - stomped on the back of it, causing it to tear? Had it become wedged under the considerable weight of Harvey Weinstein's chair? In any case, Lawrence recovered her equanimity, managed to smooth the gown back down and went on to make a rather charming acceptance speech. SEE: Beauty highlights at the SAG Awards And Dior, who designed the couture dress and adapted it especially for the actress so that it included a swishy train (yes, I think that's a fashion term), styled out the slip-up as only people working in fash-wan can. The mishap, was meant to happen, of course - it was all part of its design. "The dress is made with different levels of tulle and satin, and that is what the viewers saw when Jennifer lifted her dress slightly," a spokesman said in a statement (because dresses require statements nowadays). It was not ripped and there was no malfunction... it was the design of the gown. I have walked into meetings with my bank manager 'flying low' (the code from one bloke to another that something is amiss), and I almost opened a British Book Awards ceremony unzipped.
