Panty lines are pretty much the top answer because in my opinion panty lines are embarrassing for other people to see because they know what type of underwear you are wear. I guess I would compare it to a muffin top, you wouldn't want a muffin top to show, kind of similar.
Other than panty lines in yoga pants, spandex (volleyball), skirts. I wear them for comfort. I think that they are more comfortable than regular underwear, plus I think they are much cuter.
