well that's a little difficult for me to say since I haven't dressed in Fairy-kei that long.
But I have really noticed that the last year Fairy-kei has, among Lolita and other styles, become really inspired by this creepy, cute, halloween-ish style. and may be become a little more "badass".
Is this Fairy-Kei?
So maybe will Fairy-kei be more and more influenced by other styles and become more mainstream, so you can's see the difference anymore, like I feel it's starting to do already...
