Today a friend of mine asked me what is kigurumi. I know a little Japanese. Kigurumi is a kind of cosplay following certain rules, or a zentai based cosplay.
To do kigurumi, you must have a flesh color zentai suit, and cover your full body, including the head, a mask, and the cosplay costume. First wear the zentai suit, then put on mask, then wear the costume. The hard thing for me to do it is to get a mask I like, at an affordable price.
