Marion Cotillard – in Dior. This style review brings me no joy. I love Cotillard but I cannot say the same for Dior. The big and abundantly-skirted-issue we face, however, is not the dress itself, but the fact we saw it last year on Lawrence. On Lawrence when she won the Oscar. And fell up the stairs. And we all remember it. This might be the most embarrassing thing to ever happen to Cotillard, because in every other area of her life, she is absolutely exquisite.
