I've cut the gores - double for back, two doubles for sides and a single one for the front.
Today I inserted the side gores. It was easy because there's a seam already on the sides. The front will be worse :-(
At first I've sewn the two gores to the side and finally attached them together in the middle.
I tried to draw the neckline but there's no point taking it seriously until the petticoat neck is done.
