While I don't shame or harass people like this, I do comment and mention that people should cosplay the characters that are most similar to them. Doesn't matter what your weight/height/gender/etc is. If you can't pull off the character, you can't pull them off. It's the same as when you see a really muscular/manly dude try to cosplay a tiny feminine female character. It just doesn't work, and those people get "internet famous" because it looks ridiculous. I see no problem dressing up however you'd like (I actually encourage it), but cosplaying IMO requires a bit more planning and matching bodies. That said, I've done my own horrible cosplay gone wrong. I thought I was pretty cool at the time, but thinking back, I would've done a lot differently. And there's no reason to shame someone just because they don't have the best cosplay. Also... I don't see why pictures like that are "funny." But then again, I don't see why most stuff people find humor in is "funny." I guess I just have a strange sense of humor.
