Step 1
Trace a copy of back and front, then identify the new slash line for pincess cut: measure 5cm from high shoulder point along shoulder line on both back and front, and connect the point to dart apex. On front, shoulder dart will be manipulated in this line.
On front, extend waist line by 2cm past center front, adjust the length to 25cm past waistline, then draw the rounded hemline.
Cut through waistline to separate bodice and yoke on back and front.
