Fitting the fitting shell

I've copied off separate bodice and skirt pieces from the fitting shell. Before I go further, here's how I adjusted the fit after drafting.

• The basic pattern is supposed to have a very long front waist dart, from (below) the bust, to the greatest intake at the waist, curving to a smaller intake at the hip, then continuing straight down to the hem. The book says that this continuation can be reduced or left off if necessary. I just turned this into a normal, hip-length fisheye dart, and also reduced the intake. The smallest part is now actually above the marked waistline.
• I made the hip curves at the side seams much flatter, and they actually continue almost straight for 2-3cm below the waistline, so it's more of an S-curve than a normal hip curve. If I compare my new fitting shell to my old one, I used to think my waistline was about that much lower than I have it on this pattern. Maybe it was. Now, I have bone structure and "other structure" that is keeping my waist higher up. Before, maybe that bone structure was obscured and/or I had more "other structure" going on higher up. Or maybe I just placed the waist too low before — I could definitely see that happening with the way I worked with the fitting shell pattern at the time.
• I lengthened the centermost back waist darts by about 2cm at the bottom.
• I dropped the front neckline by a little over 1cm, and widened it slightly at the sides.
• When tracing off the separate skirt pieces, I slid in 1cm of width, half centered on each dart (increasing the dart intake to keep the waist size the same). I haven't yet tested the fit to decide whether this was a good idea or whether I'd have do something to the side seams as a result.

I'm considering doing a (probably length-only) FBA, too, or at least making a version of the bodice pattern that has one. My paper supply is getting low, though, so I might not want to go nuts with different variants right now.

Comparing this to my old fitting shell, it's surprising how much narrower it looks, especially in the bodice and the width across the armhole. I don't know how much of this is an ease difference vs. a size difference.
