Taking pictures of someone’s ass, specifically, rather than of their whole costume from the front, is a sexual act. The fact that folks are doing so furtively, attempting to avoid an interaction that might lead to their being denied permission for their actions, suggests that they’re pretty aware they’re doing so without consent. And if you know you’re sneaking around, and also want to be a decent person, that should probably make you think… Cosplay is not a permission slip. There isn’t a lower level of scrutiny for people who take furtive shots of a woman’s behind at a convention or while she’s at school. A creepshot is still a creepshot, no matter where it’s taken and what a woman is wearing.
