When I started at [Nina] Ricci, I did street wear for very cool, young girls but the price point was for the fourth floor of Bergdorf Goodman next to Carolina Herrera. My cool girls cannot afford it.

When the economy changes, it's not like you want to start eating bad-tasting chocolate.

My mother loved fashion and always had a great aesthetic. But she also considered the cost of it, with the kids, that it wasn't something to allow herself. It also probably nourished my passion and my will to make fashion, because I've always felt that, because of having a big family to take care of, she sacrificed a bit of her femininity.

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.
