Get your basic block and start by drawing the new neckline: lower 4-6cm on center front, front and back shoulder, and slightly more on center back (8-12cm).

Move 1,5cm outwards from center front to draw the button stand.

Draw the slanted slash line for the dart manipulation from the shoulder to the side seam.

Flare both front and back skirts by 5-7cm.

Cut at the waistline to separate bodices and skirts.

On both skirts, draw the line from the apex of dart to the hem.

Cut at the new neckline.

Separate the upper part of the bodices and keep the bottom parts only.

Start from the back: measure the back armhole from the armpit to the new neckline, then take this measurement to the back sleeve cap from the armpit upwards. Find a point.

Repeat the same process for front armhole and front sleeve cap.

Connect the two points with a line and cut of the upper part of the sleeve cap.

Straighten the sleeve inseam and draw a line for the bottom elastic.

Cut the sleeve in the center and spread the pieces by 10-12cm.

Draw a parallel to the bottom line 0,5-0,7cm away (depending on the size of elastic you are using).

Draw also a couple of parallel lines on the upper part of the sleeve: here we suggest to use an elastic with the same width of the button stand (e.g. 3cm).
