Step 1
Trace a full copy of back and front, then adjust length to 5cm above the ankles.
Taper 2 to 3cm from side seams at hemline, blending to zero at hips.
On front, measure down from armpit 7 to 8cm along side seams and draw the slash lines to bust points. Cut through these lines and close shoulder darts, manipulating their volume into those french darts.
