I think that one of the most exciting challenges is to see them work with unconventional materials. Because I think that– although they probably, in the real world, will not be making clothes out of garbage or candy, or going to the flower shop– I do think that you will have to make a silk purse out of a cow's ear at some point. It's gonna happen.
You're going to suddenly have the challenge of something that's hard to work with, that might not be your first choice. You're going to have to figure out, "what am I going to do with this?" So this is testing that ability to the extreme, which I think is very essential to a long career in fashion.
