I love this simple vintage look Isla Fisher sported in London last October. Not a big fan of the lilac shoes. I would trade them out for black ones. Unfortunately, I don't know the name of the bag or dress.
Recreate the look with this dress from Daddy O's Stop Staring Black Dot dress for $99 (scroll down & it's the 20th dress)
To finish off the look, pair black stockings with this purse from Asos for $62
I adore Zooey Deschanel's retro style and so do many others. By request, here are looks inspired by the following photo shoots (click on picture for bigger version or link to product).
Marc Jacobs original and copycat from Asos for $50:
