Step 1
To draft the pattern, start from a basic dress with darts and 0 to 2cm ease on bust, waist and hip circumference according to the type of fabric (if it has some stretch, 0cm ease is ok, if it is a bit stiff and/or non stretch I suggest adding few cm on all circumferences).
Draw the open neckline on back and front, then redraw armholes reducing 1 to 2cm on shoulder line and lastly widen shoulder dart by 1cm at front neckline.
