This is one costume that people still talk about, 10 years later, as one of their absolute favorites and most memorable. Why do you think that is?

It has unbelievably resonated. When we started making the movie, we all knew it was a pivotal moment and it had to be a memorable dress. Joe said that to me, right at the beginning, which was obviously a lot of pressure on me to try and make this memorable dress. But we didn’t know, really. It was a complete surprise how much it did resonate with people and how much it was picked out as a single look from the movie. Most of the other costumes that Keira wore are not talked about at all. It has surprised me, and it’s surprised me that people still remember it.
