What's the oldest piece of clothing you still own and wear?

This is a great question! :D
The one thing I still have (and wear) is my 1992 Napalm Death "Campaign for Musical Destruction" longsleeve tour shirt, with all the concert dates listed down the sleeve (Toronto - September 26.) It's seen better days but I still wear it around the house sometimes despite its frayed cuffs and myriad holes.

Go on, ask another - I dare you.
