It took her long enough!
The actress nearly offended the designer while designing it, though, telling Vogue:
"I begged him during the first fitting to make the train detachable. He looked at me and said ‘But it is a dress, not a costume.’ The memory of creating it with him is something that I will treasure forever. He somehow read my mind and designed the dress that I’d always wanted."
Okay maybe he wasn’t offended, but we’re glad she listened to the man! LOLz!
