I have white cotton Levi shirt with a rivet in the breast pocket, 'holding' the designer label on. It really buggers up the iron by scratching the ironing plate if I forget which shirt I'm doing.

All Levi's will have one rivet in them somewhere, usually on the back pocket. It's their design label, like the Steiff bear 'knopf in' meaning a 'knob' or rivet in the ear. It's how you can tell they're the genuine article.

It was a while before they took the rivet out of the crotch though.... to the delight of all those who rode bicycles or sat round campfires with their legs open.
