Hi Travolta and Seraphelle and Kerry, you are exactly right.
Gothic Lolita is not a fashion trend here, it's a very specific "movement" that's been around for...I think decades, in various forms. And yes, it is very true that these people go to Harajuku dressed in all sorts of gothic styles (wrapped head to toe in bandages, dressed as dark doctors, piercings all over, etc.) as an outlet to their "angst"; they openly admit it themselves. They have found a community there where they can share their hurt, sensitive, repressed selves with others who share the same feelings.
That's very observant of you Travolta, I think you are right; it is exactly a kind of punk movement. I think the English and the Japanese are so similar in many ways.
I also think it's a healthy and necessary outlet for a repressed country with the highest depression rate in the world...
So unless in very diluted forms and influences here and there, I doubt Gothic Lolita will ever become an all-out trend here, it's more an either you are one or you aren't kind of thing.
