Never in my wildest dreams did I entertain the idea that I would become a fashion designer.

My success was also owed to career women who maybe had big legs or ample thighs, who felt well-protected by my fluid clothing that hid their flaws.

Accessories are important and becoming more and more important every day. They can completely change the look of an outfit, and women like the idea of having a wardrobe that's versatile. For instance, a strong piece of jewelry can make a simple outfit look elegant.

Retailing has become fiercely competitive. Today there are many large global fashion companies who have opened up mono-brand stores in major cities around the world. When I first opened my boutique in New York, in 1985, there were almost no other European luxury brands present with their own stores. Now Fifth Avenue is packed with huge stores from major Italian and French labels.

Elegance is not being noticed, it's about being remembered.

Today, people no longer go out with a total look or ensemble taken straight from the runway. Customers mix and match between labels and between price points. The idea is to create something for yourself: what you want, and how you want it. I realize that shoppers want more flexibility and choice now.

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.
