I stumbled across a blog with this Vera Wang, worn by Michelle Williams in her wedding and am having a hard time finding the exact one (I did find a similar VW, but didn't like it quite as much.) Maybe it's custom? Has anyone seen it before? I am linking it to my WB post, because Photobucket is not working for me:
