Most of my clothes are old, even my shoes aren't exactly new..lol I think the oldest clothing I have is from the 70's, old Olive Drab army pants, I got them from my father because he could no longer fit in them, he got them when he was in the Army. I also have clothes I got in the 90's from thrift stores my mother took me to, clothes she told me I would 'grow' into, which actually wasn't a lie, but the clothes were a little big then, but even when I got the clothes in the mid 90's, they were still old.
Like the pair of Levi-Strauss jeans, they show inside they were made in the US. I also still wear several plaid shirts I got in the 90's, one of them I know is from the 80's. Oh, I have my DPM jacket, which is very old, I'm not entirely sure how old though.
I do have some newer clothes, but everything I own is from a thrift store pretty much.
