Unfortunately, I can't save pictures from the site right now, but they have galleries for each of the artists they've designed for, so I will link to each page. As you can see, most designs are gothic/VK/yukata based, but I thought you'd like to see anyway. I personally LOVE the katana and fan combo used for Izanagi. Again, delete if not appropriate.

If you visit the main costumes index, you can find links to each band's website/profiles. NOTE: Some of these bands are long defunct, so not all links will work.
