I'll start with the best in my opinion. Overall I loved Mila Kunis in Elie Saab and Camila Alves in Kaufman Franco the best. I don't love Mandy Moore, but thought her Monique Lhullier dress was impeccably made. Also, how charming was Anne Hathaway in that Lanvin tux and glitter pumps?!
...AND the worst. I don't love Scarlett Johansson so if she doesn't look drop-dead amazing I'll find it easy to continue...to not love her. She does have an amazing body and that dress in that color was just so blah. I LOVED Nicole Kidman in Rabbit Hole--she's so amazing but was super disappointed in her wardrobe choice for the Oscars. Kinda looks like a table runner at Christmas dinner. And Melissa Leo, loved her speech, would love to know her in person and while I've seen cutout designs work before, this wasn't Oscar winner-worthy.
