I've already knew that you are going to build an alternative fashion site in the other thread, but didn't know you are into goth, Lolita. I used to think of creating a community site for these crowd knowing that they are quite some of them in small groups everywhere, Lolita is popular in Japan and China is seeing some fans too, but there aren't yet a large community seen online, although, there are already some established cosplay and Lolita sites found.
Good luck to you
