I think this is the oldest pattern I have in my collection. It looks to be late 20's, maybe early 30's. Notice the slight stooped posture of the model. Standing like this was in style for a bit. If you watch old movies, especially those with Constance Bennet, you can see it. In the book, Complicated Women, Mick LaSalle calls it "the collapsed posture that in those days spelled easy grace."
