Shorten the skirt and reduce the hem from the sides, then draw the underbust line and all the drape lines from center front and back to the side seam.

Redraw the armhole a bit lower and the dropped shoulder.

Lower the sleeve cap to match the measurement.

Cut through the drape lines of back and front and start creating a whole block placing them together at the hem and at a distance at the waist.

Try to space them evenly.

Trace the separate pieces: skirt (mark all pleats and their directions), back and front bodices with underbust gathering, collar, sleeve (with the new sleeve cap-we made a mistake here! use the lower line) and cuff.
