These adaptations need to be done on a pattern with no seam allowances. All measurements are in centimetres (cm). In the diagrams, the green lines are the original pattern lines, the pink lines are construction lines and the red lines are new pattern lines.
Bodice Back
- Mark a point (X) 1.5cm upwards perpendicular to the shoulder slope line.
- Draw a line from the neck point to point (X), and extend this line by 5cm. Mark the end of this line (Y).
- Draw a guide line vertically through point (Y) parallel to bodice centre back.
- Draw another guide line horizontally through the underarm point. This should be perpendicular to the previous guide line.
- Measure the half way point along the vertical guide line between point (Y) and the intersect at the horizontal line.
- At that halfway point, draw a 1cm perpendicular line to the left. Mark this point (Z).
- Join up points (Y), (Z) and the underarm point with a french curve.
Bodice Front
- Mark a point (X) 1.5cm upwards perpendicular to the shoulder slope line.
- Draw a line from the neck point to point (X), and extend this line by 5cm. Mark the end of this line (Y).
- Draw a guide line vertically through point (Y) parallel to bodice centre front.
- Draw another guide line horizontally through the underarm point. This should be perpendicular to the previous guide line.
- Measure the half way point along the vertical guide line between point (Y) and the intersect at the horizontal line.
- At that halfway point, draw a 1cm perpendicular line to the right. Mark this point (Z).
- Join up points (Y), (Z) and the underarm point with a french curve.
