I wait until M & S have a 20% off and buy in bulk then so for each 4 pairs you get one free. I don't mind wearing them again if they have a small hole in the foot as I just have it under my shoe, but one of my pet hates is to see ripped/snagged stockings, and clothing for that matter, it looks minging, although I did once have a boyfriend who had a ripped stocking fetish lol Nowadays I save my laddered ones to put on cross dressing guys they never notice.
