Isla Fisher Is Amy Adams' Opposite At The Vanity Fair Oscars Party

Isla Fisher was the second flawless redhead at the Vanity Fair Oscars party yesterday evening!
The actress was elegant in a black Zac Posen gown with a tone-on-tone diamond pattern effect throughout. It had just the barest hint of sheen!
We also adore the delicate sweep train and the way the one-shoulder strap forms a cap sleeve!
Isla accessorized with Stuart Weitzman heels, and jewels from Neil Lane and Jacob & Co.
We really hope she took some pictures alongside Amy Adams as well!
They were like black and white twinsies in their similar gowns!
