Even though this thread is a year old I think this needs to say
In cosplay, who cares if people know who you are? It's about having fun. I actually really don't like cosplaying popular characters that everyone knows. Even if your costume is simple you will stand out for being that one cosplayer at con! The beest part is that it is so much more magical when someone knows who you are.
