Togas were common among the patrician class in Ancient Rome too.
There’s even a painting of GW wearing a toga , “The Apotheosis of Washington”. Next time you’re in the US Capital bldg, look
At least 2 statues of of our Founding Father that shows he knew how to toga.
So...
Just cuz it’s old don’t make it accurate for a specific time period. Or, at least common. But then again, if you want to use a roller buckle, it’s still sorta free country; go for it!
