Marc Jacobs & Robert Duffy Dish On Their Friendship, The Possibility Of Couture

Marc Jacobs and Robert Duffy are thick as thieves. They've posed together nude, they tweet at each other and they consider each other family -- "I'm the dad and Marc is the crazy mother!" Duffy once said.

Now the Jacobs and Duffy, the president of business for Marc Jacobs International, have sat down to talk about each other to WSJ. Magazine in a profile entitled, “Partnership: Fashion’s Better Halves.” Loyal though he is, Duffy revealed some interesting tidbits about the beloved designer... one being that the designer, unsurprisingly, is very demanding:

"Marc is famous for deciding things two weeks before the show, like, 'Oh my God, I want Stephen Hones to make polka-dot hats.' He expects the impossible from every single person. He expects everybody to just get with the program and get it done."

But, despite his high-powered style, Jacobs is still quite vulnerable, Duffy said: "He is very fragile and childlike."

Duffy also dropped what may have been a hint, saying offhand, "[Marc] could do a couture line." Given the reports swirling around that Jacobs may take the now-vacant creative director position at Christian Dior, and thus design couture for the first time, Duffy could be divulging the exact information every fashion insider is dying to know.

Then again, the pair have some experience retracting all sorts of material... Duffy may not have meant exactly what he was hinting at.
