One of the things that I tried to do with Sea of Dreams was to ground the world building in plausible reality, even the fashion. One aspect of this was the idea that clothes could be downloaded with different patterns so that one physical outfit could have different styles. This article from GigaOm points in the direction I was thinking about.
I could image this technology applied to a design like this one by Tex Saverio. While I don’t think the goth look would be the fashion in China during the time of the book, I could see a something like the green pattern rendered on a top. This pattern could morph or change colour randomly throughout the time it was worn.
