Sometimes you never feel lonelier than when you are always doing tons of things and traveling all over the place. There is a real feeling of loneliness sometimes.

I think creating the clothes is about creating historical images - and that's about more than fashion. It is about the fashion, the photography, what you are doing in the moment. It's what we call in French rechercher, or the search for that thing. So even though fashion is not scientific, I think being a designer is somewhat like being a scientist.

It's true that fashion is looking at fashion all the time, and this is quite boring.

We live with a future where every three or four months, we have to question everything. You think you could be the best, or that you're nothing and you don't know what you're doing. It is exhausting.

Fashion is a playground up until a certain age. But then you have to find your own signature and your own style.

I've always been fascinated by people's capacity to care. Everyone has a different capacity for it. Some people can take on more and deal with more. Today, with the economy, I have such respect for the hard work that has to be done. But we're on this planet and we have a responsibility to ourselves to care.

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.
