I think the trick is, how do you spend time doing it but make it look like you haven't spent time doing it?

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.
