What was wrong
The first automatic reading described a waist seam, a centre-front bow and a balloon skirt. After a hand correction, reviews found that the pattern had no cloth for the folds that spread from the knot, that tying the knot would pull about 9 cm out of the opening edge, and that the cascade in the photo was missing.
What changed
The overskirt is now a layer that opens at one seam. Three pivot pleats, hinged on the side seam, open 20, 25 and 30 mm at the knot and close to nothing at the side seam, so the fullness sits at the knot. The cascade is a separate lined piece, sewn to a straight edge from the knot to the tip. All three changes are in the shared engine.
