I'm from Argentina. Gauchos used to wear them with a chiripá, but nowadays not much people use chiripás in their everyday life. They are still used by a lot of people during traditional holidays for example.
In the countryside we use "bombachas de campo" as cowboys use jeans. So in winter we wear ponchos using them. Pic related is what you would wear without a poncho, and usually you would wear the same thing under the poncho. I didn't use a photo of people using a poncho cause the "bombacha de campo" wouldn't be fully visible.
