What’s the oldest piece of clothing you own/ still wear?

I have old pyjamas I used to wear as clothes to the gym, but now wear to bed after upgrading my gym kit a few years later, big floppy Gap t-shirts, that sort of thing, those are about 18-20 years old. I have a very decent but old pair of boots from AllSaints, dated 2009, I've reheeled them a few times and still wear them. A leather jacket I've had since 2011, still wear that every year in the spring/summer and autumn/winter and do have a bag from around 2011 but I need to take it to be mended (its a lined leather bag) it's old and battered but that makes it look even better IMHO. Everything else I've either grown out of, shrunken in the washing machine or just not wearing as it's not my style now. But I do generally keep everything I buy until I know I won't wear it again and then I'm selling it on Vinted or eBay. I have things which are older still but I've bought second hand so can't say those things are as old because I've not owned them that long, but 18 and 19 years is probably the oldest I would say. I was a child and wearing kids clothes before maybe 1995 and left home without anything more than basic clothes in 1999/2000 so wouldn't have had anything older than about 30 years if I did have anything, but as a teenager the things I was buying were very cheap because I couldn't afford more and those things just wouldn't last the test of time because they were poorly made so that they could be affordable.
