This blouse shape, seen in a museum photograph, is interesting because it makes use of narrower widths of fabric. The side panels extend from top to bottom with embroidery at the top portion to give a yoke effect across the entire top front. The true yoke is the center section with the flower embroidery. The center body panel is pleated to the yoke forming the attractive little ruffle. The sleeves have a ‘puffing’ section bordered by decorative braids or bands of embroidery.
Sometimes import stores have inexpensive, brightly-colored kitchen towels that I used to think were too narrow to use, but they would work in a design like this one. Also, if you came across a piece of pretty weaving or a wide braid, it could be used in the center yoke piece. You could also make your own decorative braids by using the built-in stitches on your sewing machine to embroider ribbons or bias tapes to make the decorative trims.
