A topknot would work out better on you than me; I can tell you that. Doesn't work so much on white people. Or, at least, not on brown hair. Although I had fun cutting it off and thinking of The Last Samurai part where that one dude gets his topknot cut off, or his honor getting cut off metaphorically, just really abstract screaming. Hmm. Well, I guess that's not exactly a samurai topknot. Close enough. Though your hair looks fine as it is, in my opinion. And really, long hair is really annoying to take care of.
