You can JUST tell in the landscape-oriented photo, that she is wearing something UNDER that silky satiny stripey garment; you may not have been meant to know that.  Nothing written on these 3 1/2 x 5 inch glossies to tell us where or when, but that fireplace is there, so it is part of the larger photo shoot.  The portrait-format photo has damage at the bottom: I am seeing a trend.  I suspect these photos were processed as quickly as possible for resale in the back pages of men's magazines, and sometimes got stuck to each other in processing.  Ifg you have another theory, um, keep it to yourself
