Being almost 68, I haven't had to worry about such matters in 18 years, and I've never seen a cup or even know about the panties. It was always pads for me. And back in the day, women had to wear "sanitary belts" that the pad's ends were slipped through to hold them in place. Thank goodness the sticky ones came along.

So, the cup and the panties could be better for some women?
