This is a precise close fitting bodice pattern we have implemented following our own algorithms. Don't be intimidated by the number of measurements required here, use little 'i' buttons to show explanations and let the great fit be your reward!
Note that some of the measurement are a bit unusual (like those diagonal ones). They might be inconvenient when drafting patterns manually, this is why you won't see them in books often, but they are ideal for the computer.
When taking measurements we recommend to use rubber bands for the bust, waist, and hip lines. It is easier when center and side points are precisely marked on the bands beforehand. You can also use a paper band for the neck and armscye (beware of paper cuts, fold everything!). Paper bands would work better in those cases as it's critical that all points measured on the neck and armscye are in the same plane, something a paper band or a wide tape measure would take care of.
The front and back points on the armscye can be selected by hanging a tape measure or a paper band on the shoulder, so it hangs at the top armscye point, then adjusting it slightly so it repeats the future armscye line, and then picking the front and back points on the band. The exact vertical positions of these point are not important, approximately in the middle should be ok, but they need to be in the same plane together with the armscye top and bottom points however, as they would in the final bodice. (This is why we suggest to use a band made of paper or a tape measure--they stay in the same plane.)
The point on the shoulder blade can be selected anywhere you would like the corresponding dart to appear.
The center points on the breast should also depend on your preference, they should not be exactly at the centers as some books suggest.
