I’m not really big into belts. I have two leather ones. The brown one is from L.L.Bean and the black one I think I picked up at Nordstrom Rack and can’t recall the company at the moment. They’re fairly unremarkable.
Maybe if you want something unique, look at Brooks Brothers or Sid Mashburn for an engine-turned belt buckle and get a leather belt to go with it. You could have the buckle engraved with your initials.
