Buy second hand clothes. These are either very, very, cheap, and they last just long enough for me to get bored with them. Or they are merely fairly cheap and last almost forever because the stuff that quickly falls apart doesn't get resold, it gets discarded by the person who bought it new.
In either case I have lengthened the time between manufacturing and landfill and had the enjoyment of clothes that I would otherwise not have been able to afford along the way.
