@Byeoljjang: I think you'd also look good as Kyoya Hibari from Katekyo Hitman Reborn!
@animenerd93: It is an issue if you want to portrait the character ''realistically''. Then it's better to choose someone who looks similar to you, and it often looks nicer. It's also important in groups. I get the feeling, that this is what she's aiming for.
If you just want to have fun, ít doesn't matter. It really depends on what you expect from cosplay.
