I don't buy armor that leaves belly button naked. If I have had to meet with with sharp steel I would prefer my belly button under as many layers of leather and chain as it possible. I don't buy exotic dancers with swords either. Swords are sharp. Every sensible person will keep them away from her intime parts. A story about knight who put naked sword between himself and naked woman in his bed is not some silly medieval joke.
A note for book lovers - if a hero wear hidden chainmail and feel that cold metal rings touch his body - author should take pause writing fantasy and read some books. You can't wear chainmail over naked skin. If you want your skin to survive your first walk, of course.
