Separate the top and bottom of the pattern, making sure both pieces are still attached at the underarm.
An angle is formed. The line created between the center-breast points that are now separated will be the new fabric fold. Place a piece of pattern-paper underneath and secure.
The old fabric fold is now tilted, and will be cut on the fabric and sewn later (creating a seam below the twist until center bottom).
How much to separate? Mine is 20cm, which is more than enough for a size medium / size 38 European.
Less than that will give you less “breast space”, for modest breasts. More than 20cm will be required for fuller breasts.
