Yeah, I'm pretty sure that's a guy...(I'd feel awful right now if it wasn't...
I agree with Tombow
in that older guys trying to cosplay as younger guys can be a little awkward due to the stubble...Perhaps girls predominately cosplay as characters such as Ed because they have a stubble-less face no matter how old they get --but therein lies the problem of a girl's other
physical features; perhaps sometimes they are dead give-aways that you are in fact a girl, if you get my meaning.
Or maybe girls find it more fun to dress up? xD
