This blouse used to belong to one of my sisters. It looks like a size Small since the shoulder-to-shoulder measure is less than 14″ and it only measures 42″ around at the bustline. It is different from the other two Mexican blouses I have shown in the way the yoke is constructed and the way the sleeve is attached.
The fabric is cotton, and is quite similar to the IKEA sheet I recently made an apron from. The blouse is machine sewn on the seams and hand embroidered in areas. The yoke is attached to the body with hand stitches. The gusset does not reach to the bottom of the sleeve so it retains its square shape.
The yoke is decorated with cross stitch, which is also used to decorate the sleeves and to provide a casing of sorts for the sleeve ties.
The bottom doesn’t have a hem and you can see in the photo above that the selvedge of the fabric is used for the bottom edge.
Tomorrow I will show more photos of the construction, especially of the interesting yoke assembly.
