[Plumbus]

It was not uncommon back in the seventies for a girl to show off her breasts. Either with see-through material or accidently on purpose allowing a glimpse by way of a button undone or a garment tha5t was in adequate to cover her assets. I persuade my wife that this was fashion and she often wen out wearing see through and garments that leaft nothing to the imagination.
Latterly she does not dress so boldly but is prepared to show a bit of cleavage
