I have a high school football t-shirt from 1973. I don’t think I could fit into it but I’ll never throw it out.
These days I find myself just wearing solid color t-shirts, but I have at least 20 souvenir t-shirts of various types. And I have a few old ones that I don’t care about that are good for yard work. I have a hard time explaining to my wife that a t-shirt that I don’t care about is useful and therefore valuable. The t-shirt paradox.
