Remain true to yourself and your philosophy. Changing in the face of adversity will in fact diminish your credibility with your customers.

Clean lines have always been important to me, both in terms of interiors as well as fashion. For interiors, I am more interested in textures and surface treatments than bold color or print - the vein on a wood or the shine on a lacquer, for example. I know immediately when something isn't working - usually it's a question of consistency - and I make instantaneous decisions on how to remedy the situation.

If people want to change, they will. If they don't want to, it's hard to make them do so. The current interest in the environment is a good thing. The best way to make a contribution in fashion is to promote the idea that a fundamental interest in preserving the environment is itself fashionable.

When I go on my boat or to my vacation houses, where I still unfortunately spend very little time, I don't go with the celebrities I know but with a close group of friends and people who have worked with me for a long time.

Remain true to yourself and your philosophy.

The world is changing and so is fashion.

You have to have doubts. I have collaborators I work with. I listen and then I decide. That's how it works.
