To the original poster: my girlfriend, my friend, and I are interested in cosplaying as Tekken characters for the next convention we go to. We plan on doing the following:
My girlfriend: Christie
My friend: Violet
Christie and Violet are quite easy to reproduce, but Yoshimitsu will prove to be a challenge. We're planning on using plaster for the costume design because it will remain cool and should be fairly comfortable when we attach linen trimmings to the edges of the plaster.
