VG, I am with you, my garter-wearing brother.
gdl: I have no problem finding OTC cotton socks in NYC, nor do I have your bad luck with wool socks shrinking. I do hang dry mine, but that is pretty easy to do, and it does not take a lot of time.
I guess my answer to the OQ would be that I still wear a college-era Land's End braided belt sometimes. Not with suits, but with odd jackets.
