I want to be a little bit careful, because there may be someone who actually judges someone’s work by the fact that they cosplay, but jeez, that would be one lousy editor.
I guess it is possible that some editors might be that small-minded. I hate to think it, I can guarantee that editors USED to think that way and used to mock cosplayers openly, but I would hope they had outgrown it.
I feel like you should still go ahead, if they genuinely care that you are cosplaying, break in anyway just out of spite.
