Alterations to back and front. Additions are cyan and subtractions are yellow.
a: shorten overall armscye depth; b: for forward shoulder, make the shoulder line squarer in back and more sloped in front, by adding and removing length, respectively; c: to raise the bottom of the keyhole without changing the neck/collar seam, shift the bottom of the keyhole upward by removing length from within the keyhole and adding it back below.
d changes the waist length and also creates a bit of a cheater FBA: the waist length was originally too long on the back, and shorter than my fitting shell on the front, presumably because the fitting shell has a bust dart and this pattern does not. The lengthen/shorten lines were adjusted accordingly and the front was then eased onto the back above the waist.
e adds at the hip, more so at the back and with some additional length to make up for the waist length removed (and because I often prefer the hem to be longer in back anyway).
The keyhole facing has to be shortened to match alteration (c) on the front.
f: shortening the sleeve cap and moving the shoulder notch forward (original blue, new magenta) to match the shoulder and armscye depth alterations that were done on the front and back pieces.
g: I increased the bicep and pivoted each half of the sleeve cap so that the overall sleeve cap length would remain the same. This results in the cap height becoming shorter. (Since I had already cut that part off before taking the photo, the size and shape of the yellow area is approximate.)
h: shortening the sleeve length
