You yourself refer to her "slutty look." I don't see how my trivial observation that she looks like a cheap, used prostitute is any different an estimation. I agreed with you, that it's a subjective aesthetic taste, no real right or wrong here, up until you threw in the judgemental prick. I don't see the need for that. I doubt you could find any poll of the global human species where anything short of an extreme minority could look at that picture and not to some measure agree with my estimation.
I worked with a girl who got out of prison and was short on money and said "I guess I'm going to have to sell some kitty" and then did. As far as I'm concerned, disgusting, but I didn't judge her or treat her like less of a person. She was good people. Just not my cup of tea. That's all.
