Rachel McAdams in Elie Saab Haute Couture (left at the Vanity Fair party and right on the Oscar red carpet - notice how the light changes the colors, I like how much warmer it appears in the daylight) What sold me on this dress was when she walked out on stage, it just looked so divine.
On the runway roughly 6 weeks ago (it was the opening look on Karlie Kloss no less)
Here is my after party pick:
Cameron Diaz at the Vanity Fair party in Victoria Beckham
Here's the dress from NY Fashion Week just a few weeks ago.
