Cheap makeup is atrocious. You can smell it from a metre or two away and on a packed subway, it's positively disgusting.
Aside from that really cheap garbage, if a woman wants to cake makeup on their face then they can go for it. I won't even think less of them for it if it's caked on half a centimetre thick from social pressure because that type of expenditure keeps the economy healthy and all. But I will think such caking is ugly.
A fine amount to draw out features (ie, eye shadow, minor blush) is a different story. You know, the type where if you poked it with the tip of a pencil, there wouldn't be an impression left behind.
The issue here is that most youtube videos are about the former scenario: the caking. I mean, on a rubbishy low res upload, that caked on stuff is like an airbrush. What's good on video can be a fail on the street. Can you really blame a commenter for upholding stage makeup passed off as casual street style as if it were for the street?
