This isn't Art Nouveau by any stretch of the imagination. This is just another insipid Kawaii riff with some fringe behind it. It totally escapes me how designs like this one are always doing well. My wife has purchased over 40 Woot shirts, and I was going through them the other day: only 3 were derby shirts (two RamyB's and one Spiritgreen), and the rest were dailies (and not a one by Walmazan).
When I see designs like this one doing well, it completely explains why we never buy derby shirts.
