So not only was Mark Zuckerberg’s marriage to Priscilla Chan a surprise. Her wedding dress designer, Claire Pettibone, was surprised to learn her dress called “Sky Between the Branches” was chosen for the billionaire boy’s bride-to-be.
Using a different last name, Chan selected her Claire Pettibone dress at Little White Dress Bridal Shop in Denver last fall and gave the store no more information other than the date, May 19. All other arrangements were made through a third party friend.”
Brides Magazine also has clips of the dress from the runway. http://www.brides.com/blogs/aisle-say/2012/05/priscilla-chan-wedding-dress-get-the-look.html
