Step 1
Trace your block with darts (and zero or negative ease) up to 8cm below waistline.
Draw the new neckline on front:
- start from center front 12 to 14cm above bust level
- square across past the dart, up to 5cm before armhole
- draw the new armhole quite flat ending 3 to 5cm below armpit.
Draw back at matching level at side seam, 5cm wide at top, then a slanted line to waist at side seam (you get something like a triangle).
Mirror front to have it full.
