Step 1
On back and front:
- draw the new neckline (5-6cm above bust point on front, then at the armpit and 2-3cm below its line at center back)
- draw the shoulder strap from the shoulder center to the shoulder tip
- taper the skirt at knee (2-4cm) and flare at hem (5-7cm).
On back, shape the center to follow the back curve and draw the panels by flaring approx.10cm in each. Flare also center back and draw a short train (15-20cm).
On front, draw the slanted slash lines as shown in red.
