It’s a shawl and brooch. It’s basically just a rectangular piece of cloth with a pin holding it together. If you wanted a slightly fancier version, you could try finding a serape/ruana instead. That’s the same rectangular piece of cloth, except it has a slit cut from one edge to the center. So it can drape over your shoulders instead of wrapping around them. Sort of like a poncho, except the cut goes all the way to the edge of the fabric instead of just being a neck hole.
