Trace front to hipline and mirror it to have full front.
Drop armhole by 6 to 8cm, then reduce shoulder top this way:
- from high shoulder point, move sideways along shoulder line 2 to 3cm
- from shoulder point, move inwards 5 to 6cm.
Redraw neckline from the new high shoulder point – if you want, drop neckline by 1 to 2cm in center front.
Erase waist darts and straighten side seam from armpit point to hip.
Get back (not shown) and change side seams and armholes the same way.
