I found the dress in the 1st two pictures on an editorial in Elle magazine but they had no references about the designer, only the photographer (which I believe it’s bad journalism, in this case). So, Elle just made me loose 20 minutes of my life searching for the designer on the internet.
It is Giambattista Valli Fall 2008. I had a hint it could be him so I had to spend some time on Style.com, searching through all the collections. It was worth it! The dress is amazing, such as the other 3 which closed the show.
