Nifty little article with loads of pictures. I enjoyed this.
Surfer Material
Amanda Seyfried braves the chilly night with a little help from her black, modern Balenciaga dress made of neoprene – wet suit material!
(Note to all the ladies, when the time comes, and Lord knows it happens to every woman eventually, when you are offered a neoprene evening dress. Please, just say NO. lol)
Girl Gone Givenchy
While Amanda Seyfried sported surfer material in her black Balenciaga dress, her co-star Anne Hathaway stole the show in a backless, ivory Givenchy Haute Couture floor-length gown at the world premiere of "Les Miserables" in London's Odeon Leicester Square on Wednesday.
