Vintage 70s Mexican Embroidered Peasant Blouse

Vintage 70s cotton peasant blouse with embroidered cut work accent. This belonged to my aunt in the 70s. No size or fabric tags, please see photos for approximate measurements. This blouse is cut generously, so could fit various sizes. Elastic neckline that can be worn on or off shoulder. There is some discoloration around neckline & sleeves (pictured). The cut work does show some wear due to its age. Cinco de Mayo, Fiesta
