Is it because they depict children or because they depict child like features?

By the first, technically adult characters in a child like body (lucky star) wouldn’t count.

By the second, catgirl cosplay counts as bestiality.

Things get seriously vague once you consider diverse aesthetic cores, like goth loli fashion. also technically is.

Is it pedophilia if you wanna have sex in a ballpit with your adult partner while dressed as clowns while sucking oversized pacifiers? Just asking.
