Then the SA told me that apparently HB's boss Oscar Pinto was informed by Yohji Inc that any topwear available in sz 1 ( except AW11 ) was originally made for Yohji-san himself, i.e. his personal wardrobe ( SS11 Priest Shirt, AW12 Blanket Blazer the other I know of ). Don't know if there's any truth in it cos someone once said also that the man himself wears sz 3? But I have seen how thin Yohji-san is in person, and he is stick thin.
This is interesting David, I've seen at least 3 SS11 jackets in size 1. In my limited experience I associated size 1 to garments not available in size 2 (priest shirt for example) but that AW12 blazer puts that theory to rest.
