They aren't natural, they are cultural, and based upon the desire by humans to exercise control upon others through shame and intimidation.

I don't know why, but that's what I honestly believe.

Left to ourselves in a more natural and nurturing environment, we'd all be buck nekkid!

we might have lost our fur and footpads after we discovered how good we look in clothes.

Ooops, wrong group...

Not just for attractive young women, but anybody. Clothes are protective of course, but can signify status, so in that way they divide. If someone dresses oddly, or out of gender norms certain assumptions are made. A man in a suit gives a different impression than a man in a flannel shirt and work boots. I think clothing can profoundly affect opinion.

It would be interesting to live in a world where the only clothing oddity would be the weather--- if someone was running around naked the cold.

I wonder how social barriers would change? If the little tells clothing gives off weren't present?

Being human, I suspect we'd do more body art, because for all our lemming like qualities, we feel ourselves to be, and experience the world as individuals.

We need extra protection since we lost most of our hair and our feet got tender. But people invariably attach symbolic importance to every damn thing around them, and clothing is also adornment and an indicator of social status.

I expect in these post Cartesian times the "scrim" that exists between us and everything and everyone else is especially pronounced. Clothing is an important part of how we define ourselves to others and to ourselves.

If we removed the barrier of clothing, would other concepts appear to take its place. Ideology abhors a vacuum.
