This one has been coming for a long time!!!
It's already taken over the streets of Japan (namely Harajuku +surrounding areas) as prevously stated, and is quickly making it's way around underground +sub-cultures in Europe and America.
The full blown gothic lolita is probably unlikely to emerge as a fashion, most probably stay pretty much underground, but already a momentum of it's diluted self is growing and designers are picking up on the underground as often they do.
Wether this is after having seen the subculture, or merely in reaction to the recent trend for "ladylike" and prim fashions I don't know. But there's definately a rising...
I kinda hope it does continue to influence as I like the style in a diluted form.
