I typically retain clothes for 20+ years.
I'm pretty impressed by that. The longest I've been able to make something last before it's wearing through from being threadbare is a t-shirt and that was a little over 10 years. I think my clothing longevity will decrease now that we're FIRE because I have the tendency to wear the same half dozen or so articles religiously because it makes life easier having less clothes.
Not so amazing when you know that I did use work shirts/t-shirts and blue jeans/slacks (~150/yr Company subsidy). Also, I have a 15 T-shirt (band logo etc) stash, and another 15 shirt stash of long/ more formal short-sleeve shirts that I rotate consistently.
Of course I have a shirt from a Taiwanese laundromat from 19 years ago in the cellophane/plastic wrap.
My longest term shirt is a high school track shirt (too small for me, given to my wife to wear at reunions) from 36 years ago. It is getting thin.
I retain my old motorcycle jacket 35yrs old (can't zip it up, too fat) and a special Black Happy T-shirt (26years old) for concerts.
Black Happy T-shirt--- large letters on front AND THE GEEK SHALL INHERIT THE EARTH.
