I'm considering making Teru's Masquerade outfit as well. My friend sent me enlarged scans of the book, and we confirmed that his (and Hizaki's) outfits are definitely made out of either white jacquard or brocade. I managed to find the brocade I need at the store, but since the place was closing down, it was all gone by the time I decided to go get it.
No matter what it is though, my wallet's going to cry. Lol. xD But then again, I need to finish the other two I'm already working on first, orz.
As for his hairstyle, I actually like the soft flipped look more than his usual styled-to-death spikes.
