Before anyone asks, I probably WON'T be wearing my Chii cosplay at Kumori Con. It takes over an hour for me to get into it (Yes, I'm sewn into the silly thing), and it takes that long for me to get out.
The wig is a nuisance, and the corset is... icky. >.<
Unless someone is really bored and wants to volonteer threading and sewing me into the thing at some odd, ungodly hour, I say never again. >.<
And people, please wear your badges at all times. Yes, it looks cool to take your badge off for the pics, but then you forget to put the badge back on, and then you get yelled at by neurotic security personal (we are all neurotic by the third day, usually the end of the first.), and it just leads to headaches.
Think of wearing your badge in the pic as a sign of you BRAGGING that you were at the Con! That's what I did. (Actually, the badge clip was helping keep my Chii costume together, but let's not go there >.< )
