In her Closet: Marc by Marc Jacobs & Hermes

Victoria Beckham stunned LAX wearing this retro inspired MARC by Marc Jacobs dress with her matching purple Hermes ostrich skin Birkin and plum Christian Louboutins. This dress was on sale at www.net-a-porter.com but it has unfortunately sold out (no doubt its because of Mrs. Beckham). However, you can still get it from Neiman Marcus and Saks. The dress is called the Heart leaf Print dress. The one available to buy is a tan colored but Victoria's was red - which I think is much cuter.
