I didn't know that the normal way I live my life is anything worth commenting on. I still wear clothes from when I was in college 25 years ago. But this is more from laziness and a generally dislike of shopping, combined with zero fashion sense, than from any altruistic values.
I try to only buy good quality clothes that are made to last, then I wear them until they develop holes. I repair them and wear them again until they don't really look presentable anymore. At that point they become home/work/workout/concert clothes. When they can no longer be repaired, they become cleaning rags.
I did not know that this was something to be applauded for.
