Very Funny, I sent a somewhat demanding e-mail to their press office asking if Margiela was still in the house just a couple of days ago...
The problem is that Margiela has built his appeal on using high concepts - and then translating them into purposeful, timely, and extremely chic clothes. Russo is grossly underestimating how much skill and how much of a singular vision that takes.
Despite that MMM has always been officially referred to as a "collective" it's no secret to anyone that Martin's own design direction was integral to their output. And let's say it weren't and that the team was perfectly capable of doing it on their own, they are taking direction from buyers and production lackeys at Diesel...there's a reason why some Margiela right now could easily be confused with Dsquared cast offs... not too hard to switch the labels around....
