While I 100% agree with the sign, I don't think that cosplay is appropriate for walking the floor at comicon. Maybe I'm just becoming an old prude, but that girl is practically nude, and comicon is an all-ages event. I'm not saying she deserves to be harassed, and I'm not letting anyone off the hook for being a creep to her, but that kind of cosplay should be reserved for photo shoots or adults-only environments.
