American women often fall into the trap of, "Oh, these are my weekend clothes. These are my work clothes. This is what I wear at night." It's so old-fashioned. The French are not afraid of their luxury. Americans can be so puritanical and think, "That's my special-occasion bag." Whereas, for a French woman, it's her everyday bag.

It's funny when I hear people complain - particularly about the most fabulous parts of being a designer, like when you're getting ready to work on a show. I don't even know that I'm tired. I could stay up for six days straight! No drugs, no coffee, no nothing. I'm just so excited.

Seventy per cent of the clothes you own should be meat and potatoes. Thirty per cent should be icing and fluff - that's colour, pattern, shine, accessories. Too many women get the proportions the other way round, then can't figure out why they can't get dressed.

In early days, I showed everything I made. There was no such thing as editing a collection. In the '80s, it got to the point where we'd have shows with a hundred looks. You'd want to order a pizza before it was over!

I can sketch up a storm, and I'm very involved in how clothes are constructed, but I have a short attention span.

North Americans as a whole need to embrace having clothes altered to their body. I hear it all the time: why do the Europeans always look so good? They have a relationship with their tailor and spend the time and money to make their clothes look their best.

China is exciting because it is an extremely curious and interested market. What more can a designer ask for? The client here is bold and willing to try new things, which a country with a long fashion history wouldn't dare. France or England is weighed down by all these rules, elaborate etiquette, do's and don'ts. Things here move incredibly quickly.
