Furuba is one of my absolute faves! I've cosplayed as Tohru (and I probably will again, since it's so comfortable ^^). Here's a pic of it: http://images.cosplay.com/showphoto....t=500 &page=1
I almost did Tohru in that puffy lemomy lolita dress she wears in episode 19 (I think), but I lost interest.
There was a transformed Kyou and Momiji at AX this year. They were both so adorable! I have a few pics from the AX Furuba gathering on my cosplay site (hint: click on "packs her bags" ^^)
