What, no one told you? Nooooo. You didn’t have to throw away the whole pair. When one leg gets a run, cut that leg off up around the panty line. Then, when you have to cut another pair up, just wear both good halves as one complete pair. You get 3 pairs out of 2! Those also stay in place better than a new (no cut) pair.
Those no cut pairs always hung down in the crotch which caused all sorts of discomfort. Simple solution to that, too. Wear your panties on the outside to help hold up the pantyhose crotch.
That all sounds terribly complicated and uncomfortable. I’ll stick to my garters.
Don’t forget that when they do run you can cut off both legs, tie in a knot, put conditioner on your hair, place it on your conditioned hair, work for a few and have the best conditioned hair on the block. :D
