Step 1
To draft the pattern, start from a basic block without darts and add the ones at waist to create the yoke/shaped waistband.
Widen neckline by 2,5cm on center front and shoulders and by 1,5cm on center back.
Draw a line 4 to 6cm below the waist and trace the whole upper part on a separate paper.
Draw a line 20cm below the waist and trace the piece from waist to this line.
