I've been noticing this more of a trend at cons lately, and I like to see how the characters attire and appearance is altered to create the opposite gender version. It takes a lot of creativity and insight to pull it off well, so I say kudos to anyone who attempts it. n.n
I took a photo of one such cosplayer who did Kakashi at A-kon last weekend (if you are this cosplayer, please PM me, I can send you the high-res versions if you'd like. :3)
I was really, really impressed with her cosplay. @_@ Was so very beautiful and detailed.
