Disclaimer: I realize fully that pastel goth is not a part of the traditional Goth subculture and that there's a lot of dispute over whether or not the style can even take on the moniker of Goth (but I think it's a rather silly thing to get pissy over, so I'm ignoring it), but I fully adore the style and often-times consider how to incorporate it into my own wardrobe.
Which brings me to this question: Is it possible to rock a legit Pastel Goth outfit without having pastel or otherwise colored hair?
Honestly, it's hard to find any pictures on the internet of girls with natural colored hair sporting a pastel goth outfit. And I'm not talking about this nu-Goth stuff (though I enjoy that too!) with lightly colored hair. The two simply are not the same thing. Even so....it was difficult. But I did manage to find a few photos lurking around that might give one a good idea how to rock a Pastel Goth look without bleaching out your hair or investing in a pink wig. ^_^
So it would seem that the answer is: Yes. Good to know.
