Vintage Embroidered Boxy Peasant Top

Found this at a thrift store in Temescal Canyon years ago and this is the real deal! It's a starchy linen base with yarn embroidery, vintage wear as far as pilling and spotting, but excellent shape for a piece that is probably from the 60s. No indication of size, although it seems to be a medium hinging on large, definitely meant to be worn loose.
