Cute clothes, mostly along the line of printed caps and t-shirts.

Manic Panic
Source for "punk" and Goth hair colors, cosmetics, gift items and more--"tested on celebrities, not animals." Thirty years in business and now bicoastal!

Teeth By Dnash
Website for professional crafters of custom-made prosthetic fangs, contact lenses, and other costume/makeup details. Includes descriptions and an informative FAQ. I've heard good rumors about the quality of Dnash's work, so if you've been looking for a place to get fangs and lenses, this might be the answer to your quest! Also links to sites about Dnash's band.
