I tend towards wanting to wear things until they get holes in them! But I sometimes discard other items that are pilly or bagged. I have long suspected that my standards are somewhat lower than most of YLF on this! (as in, I wear stuff that others would have discarded as too Shabby)
My take on this has been to be VERY disciplined about how much I buy. Only one casual sweater for each winter ( and some I have skipped) which may be worn 3 times a week the first year, once a week the second year if it still looks good and then a few years of being demoted to house wear.
One jacket a year has been plenty (and in terms of wear, I could get buy with less) It took me 5 years of wearing my first pleather jacket for it to start cracking and only then did I replace it.
Of course, sometimes I make mistakes etc but that is my ideal.
I am loving the fact that now I am at work I am lowering the CPW on my old work clothes and other clothes that I bought more recently but tended to be only worn on Sundays.
