I worn them. They're nice.

They're standard issue if you hang around punk-adjacent subcultures like rude boys or the not racist kind of Skinheads.

The frumpy corporate fashion of the 90s killed them

Belts got cheap to make. Suspenders work better for larger gentlemen so when fashion turned to thinner bodies belts were the obvious choice.
