Kawaii

After all the minimalist androgyny (predicted, realized) is over, girls and young women are going to get all Japanese-style kawaii.  This is sort of what Lady GaGa does already, and actually what Gwen Stefani does with Harajuku Lovers.  I don't think it'll just be the decora-chan style of Harajuku District, though --

I think maybe it will get more mainstream to dress up in a costume, like goths here already do, or as the Lolitas and others do in Tokyo:

It's predictable since what's popular in Japan becomes popular in the U.S. oh like 15 or so years later, and also because it's a very appropriate style for celebrities and, later, people who are apparently all becoming "avatars" of themselves through fashion.

I put that in quotes like to be sarcastic, but the whole public-persona-as-avatar concept is actually really cool.
