I used the shaping I had done on the calico sleeve as a guide, but tried moving the pleats from the top so that they were round closer to the body. The shape definitely looks better when the arm is curved towards the body.
When it was all pinned in place, I fitted the bodice to check that the elbow or lower arm would not pull or get caught when flexing. It all seemed to work well.
Once I was happy with the shape I had sewed the pleats and cuff folds in place and then finished the facing.
