Well, it's not exactly a runway, it's Christian Dior's pre-fall 09 showroom and Rachel Weisz didn't exactly order it right off the runway either (or wear it on one) - she got the look in a different fabric, but the same color. And boy, is it her color. She wore the dress in Cannes while promoting her movie, Agora and we think this is the most beautiful we've ever seen her.
