Aside from vintage items that are new-to-you, what is the oldest thing you have that you still wear?

I just pulled out a jean jacket that I wear on occasion that I've probably had for at least 20 years. It was originally jet black but despite attempts to re-dye it, it is very much charcoal grey at this point. But it's not frayed or worn anywhere so I do wear it occasionally.

How about you?
