I have what I believe is an early 60s dress, made of silk satin. It came to me with a generously-sized shawl. One of the shawl is looped over, gathered and sewn, creating an opening that tapers to one side. The most obvious thing I could imagine doing with this was to put my arm through it, and it goes on, but probably not all the way to the shoulder even on a very small person. How would this have been worn?
