If I were to find something that is going to be more important to me than fashion - that would be work and love - then I probably would let go. That's a possibility. But fashion is an addiction.

Why isn't Tilda Swinton on the covers of tons of magazines? Well, she's not that. It isn't her thing. But I don't know. I think that suddenly a time came when models, after the Linda Evangelista crowd, and Naomi Campbell and Christy Turlington, when the models for me became a bit bland. But I think more than that, the culture changed. The movies, television, music, and all of those things - those people were more visual and therefore more interesting.

I'm always curious. Every day. As we get on in life, we must be grateful.

That's what I think when people do their "best stuff" collection. When you start to think, "Oh, I will just present my 10 years of work," that's not a good sign.

I don't know if that's new, but it has become very official over the past 25 or 30 years - and today it's probably at its most extreme point, where sometimes collections look more like a stylist's work than a designer's signature.

With my designs and my ideas, I want to please myself first. I'm always very stressed about making a new proposition every season. But in a way, it's a kind of addiction. In another way, it's a crazy pressure. I try to stay quiet about the whole situation, because fashion itself can be crazy, and everyone wants a part of you.

As designers, we do so much with material and construction. It's really architectural; it comes close to building. A scent is so immaterial. It's really about emotion and sensation. Clothes are too, but it's not the same.
