Troy, have you ever found any period photos of the "classic" white shirt and pants for a peasant outfit? Maybe I'm not searching right, all I can find is some of reenactments of the revolution, with all identical shirts, pants, hats and red bandannas. I doubt they really were all that uniform. In period pictures from the Mexican Revolution, I rarely see that outfit-mostly cowboy/vaquero outfits, or "townies" standard period pants, shirt, sack coat.
