This is why I prefer the sort of content with just really see-through clothing, or very flimsy, suggestive clothing, with the occasional little peak.
Aside from the fact that I just find that much more attractive, but I think it also indicates it was done in a real public setting.
Plus, I don't really find the idea of someone walking around just completely naked, all that alluring. I enjoy the tease and the feeling that I'm seeing something I'm not supposed to. When someone is completely naked, it doesn't make me feel like that.
