Panties under tights or pantyhose. Here is my theory. If I am wearing say, a leotard or bodysuit with the tights, and the panties would show, I don't wear the panties. If I am wearing pantyhose or tights under jeans, my choice is high cut panties, with as little panty line as possible. Haven't worn mens underwear in at least 10 years. And now that the weather is colder here in the northeast.... tights are always on the menu. The higher the lycra content, the better.
