XD I am afraid of Sexy-no-Jutsu cosplayers, if I must be honest. I've seen far too many girls with no idea how to properly make something like that running around in cotton balls at conventions, looking like, for lack of a better term, jailbait. Then again, I've also seen some really overweight girls try to pull it off too, and while I don't like to discriminate against people based on anything, I'd really rather not see that. XD
In fact, I don't think I've ever seen what I would call a good Sexy-no-Jutsu costume. XD Not once in all my years of cosplay.
Though if you did it well, I'd like to see pictures someday so that I can no longer dislike Sexy-no-Jutsu cosplayers. Did you do the "clouds" Sexy-no-Jutsu (that's the one I always seen done horribly), or just a girl version of Naruto in his normal outfit?
