Comic Con costume help please

I'm going to my first comic con in about a year. I know that's pretty far away, but I want to find a good costume in advance. I've had a couple ideas of who I might want to be. I was sort of thinking about going as someone from the X-Men or Gert from the Runaways but I can't really decide on anyone in particular. I was hoping if I posted a picture of myself here, I'd get some suggestions on who I should go as. I'd really appreciate the help, thanks ^^
