I must say: I really love this character. She's awesome. I wanted to do her because I like this anime but nobody cosplays it, and Itsuki came as my first choice. (Oh, and I only did the masquerade like this, most of the time I walked with her ICP suit.)
Other reason for doing this cosplay: the challenge! It was my first time dealing with something so thigh, transparent material, and in this shape. And I'm really glad of the result. And the challenge of hiding what must be kept hidden is always there too... XD
