As for the costume, that sounds great (and kinda explains why the colours mattered so much to you :p ) Hope you manage to get it done in time. We (my roommate and I) have themed parties once a month, where we pretend to visit different countries, and the next country is Japan. One of my friends is therefore trying to create a Yoshimitsu costume in time for that. Gonna try to make it like my Yoshipie, which is what I call my main customisation on T6 BR. (basically, we'll cutting up a black and white duvet cover ) It won't be nearly as good as yours, as this is very last minute, but it's really fun thinking of ideas for it ^^
Best of luck to you.
