Vintage Guatamalen embroidered jacket/shirt

Amazing 60s/70s vintage jacket or button up from Guatemala. Flaws: some minor overall wear and slight fading. One button missing. A small mark on the bottom of the back. One small thin spot/hole on the back. See pics. Still a really cool unique piece. See all pics and questions are welcome. 🌻 No fabric or size tag, so please check measurements to assess best fit. Fabric feels like a cotton to me. Listed it as a medium. Approx flat measurements: Pit-pit: 21” Shoulder-hem: 26” Sleeve length: 21.5”
