Perhaps there was something in the London water in April 2001, because last year we flashed back to Renee Zellweger wearing a surprising sheer ensemble to the Bridget Jones’ Diary premiere, and this year I stumbled on a photo of Keira Knightley at the same party in this. (Apologies to Thora Birch for dragging her into this, but it was the best shot of Keira I had.) The context: In 2001, Keira had tricked moviegoers and even her own mother on-set as the Queen Amidala decoy in The Phantom Menace, but had mostly cobbled together nice reviews for smalltime work until her break in 2002’s Bend It Like Beckham. That began shooting about two months after this photo was taken. So at this time, she’d have been a relative unknown, but maybe a One To Watch. And thus, nowhere near a stylist. I just did the math, and she was 16 in this photo. I love imagining Keira coming downstairs in a bra and her mother shouting, “Keira Christina Knightley, you go put something on over that bra right now,” and Keira smirking, “Great, I’ve got just the thing,” and skating out of that house on the actual sheerest and merest of technicalities.
