Rachel McAdams was in Cannes promoting Midnight In Paris, a Woody Allen movie in which she is quite good if I remember correctly (and — I believe — on which she met and started dating Michael Sheen). For the premiere, she picked a Monique Lhuillier that a) looks like a knockoff of a mediocre Marchesa, and b) only works when she’s standing stock still. From the photos, it seems like it was a real pain in the train, so to speak.
