Very sure these thoughts go through everyone's mind anytime it's mentioned. Museum, art exhibition. Even those haute-couture (!) "fashion shows". Who buys them? We the commoner will ask? Who wears those? Oh it's fashion, they are taking photos of the clothes. Rubbish!
I don't want to not say these sells stuff. But at the same time, we could think these sort of nudity or nude space, is still about perfection. There is very little, "normal nudity". They are getting some six seven packs, greco face. Nostrils too. Ever notice why the main actor never have some "ill formed nostrils, ie. big, or flatter so to speak"? /
The bad guy, perhaps 75% of the time will be that. Will be pudgy, or just not the perfect body.
