The findings do not surprise me. If God wanted women to wear bras he would have made them that way. And when man tries to perfect what God does man always comes up short... as in your research that suggest additional sagging with time. I think there was a time when the bra was used to bring discretion to the breasts. However in the past half-century I tend to think the bra has been used to draw attention rather than discretion.
