How did the Roman’s actually wear their pugios? 2 belts?

[Tarbicus]

I'm fairly certain that in most examples the pugio belt is the apron belt and worn underneath the sword belt. There are one or two examples where the apron seems to be from the top sword belt, but could as easily be the apron pulled under and over both belts for show. IIRC there's one example of both the sword and pugio seemingly on the same belt, but that could easily be a misinterpretation of the sculpture, as the tie rings on both scabbards aren't visible.
