Hello, I'm a beginner trying to make this 1890s short jacket, and I was wondering what these flaps on Diagram 20 added onto the half(ish)circle at D and G are for? (These are also the only instructions there are, so it's not stated on the next page in the book) Thanks!3yr ⋅ Oxygenmolekule ⋅ r/HistoricalCostuming
