My sense of designing is a mix of intuition and intellectual control.

The only shoes that look futuristic are Crocs, but they would be terrible to use in a futuristic movie.

I don't think couture will die. But it should have no pretension that it will conquer the world. It's not something that will disappear because all you need is a thread and a needle to start making something couture.

I don't like to go beyond modernity because you think girls might be like that in five years, but in five years what I see now is going to be old; we are always going to go somewhere else. You have to bring a few novelties within what will remain.

Everything I have is ready to wear, but I have the ability to have different options within the same brand. I have the Theyskens' Theory collection where it's a personal approach to how I build the collection where I fuse more fashion-y ideas and it has my name on it. So it's really something very research- and labor-intensive. And then I have the Theory brand where I infuse all points of view about fashion at large, and it's more global. It's really about making something succeed. You have an instant relationship with stores, and with sales teams, and people that are in the place.

I could live naked... I love it.

I rarely stay at home when I'm in New York. I'm always doing things. It brings you so much energy.
