The wedge in the back on the right side resulted in a prominent "dowager hump" on my upper back. A slight bump was actually there already, but this really made it stand out.
I tried straightening the seam in the affected area, which cleaned up the hump. However, left lapel started gaping again, and pulling away from the side of my neck.
Rather than play with the shoulder seam to correct this, I decided to try a different way of taking the wedge out of the back, shown as a 1959 Rundschau method in the Cutter and Tailor forum references for dropped shoulder. This puts the pivot for the wedge at the top of CB seam, so does not affect curvature of it.
The resulting pattern change is shown here (figure on left replaces right). After the first try-on, I also flattened the upper back slightly as shown - about 1/8".
I patched in a piece of fabric (note to self: INLAYS! INLAYS!) and recut the right back. Here's how the resulting mockup looks:
There is just a little wrinkling at the shoulders and back of neck, and below the shoulder blades. Is this telling me the back is too long? If so, can I shorten it without popping up the lapels again?
