Looking at that modern statue, I can‘t help but be bored. It doesn‘t draw my attention. I think that’s because it depicts a normal, everyday clothed person. We see those everyday. It‘s something mundane.

A naked statue is more interesting to me. It‘s less a depiction of a person and more of mankind in general. It has an abstract but intimate quality, inviting to reflect (wow that sounds posh).

Cloth was presumably expensive, and so perhaps you would only own a few items of clothing, and therefore might not wear clothes every day? Or maybe only clothes for some purposes like for fighting (armour)?
