A quote from him which he said in an interview which was in Elle, last year around November...
"I am never happy. Happiness scares me, then I am afraid to be less happy. Happiness is a very dangerous state of mind."
this quote reflects what his Fall 2008 r-t-w collection shows. But i have to say, although most of his pieces are dark colored, they are truly magnificent.
