I decided to invest some time in improving the shoulder fit on this tunic since it's a really simple pattern that could be easily adapted to create other styles. So I consulted Fitting & Pattern Alteration: A Multi-Method Approach by Liechty, Pottberg and Rasband.
I picked this up after I heard Susan Khalje mention that it is her favorite fit book. I haven't used it much yet, but so far I like it's technical, no frills approach to analysis and correction of fit issues. Each fit issue is addressed on a 2-page spread, and the chapters are broken out by body area - hip, torso, neck - which makes it efficient to flip through looking for your particular issue. They give you line drawings of "the wrinkles" that we love to analyze, and a text description of the underlying structural reason for them. Then they describe how to resolve the issue on a fitting garment and on the flat pattern pieces. I get lost reading the text, but the pictures are understandable for the most part.
Here's my altered back bodice piece where I cut open the back in a few places so I could move the shoulder seam forward by half an inch. Extra fabric is added to the back to accommodate the fact that the armscye is moved forward.
Now, the sleeve pattern piece. The F&PA book shows how to alter a sleeve for a forward shoulder adjustment, but I just don't get it... Then I found this tip on Pattern Review which sounded simple enough, so I used that method (literally, slashing the piece horizontally underneath the sleeve notches, moving the cap forward the necessary amount, and redrawing/truing the seamlines) to start with.
I muslined that sleeve piece and found two issues, (1) I didn't like how much ease was in the sleeve cap (1.5") and (2) the angle of the sleeve felt very restrictive - it was fine with my arms by my side but tight when I raised them.


When you remove sleeve cap height, you are really just redistributing the armhole seam by giving yourself more width in the arm (the length of the armhole stitching line is unchanged so no adjustment is necessary to the bodice!). This is exactly what I wanting for this tunic - a slightly looser, more flowy sleeve.
Now I've got my silk fabric cut out and I'm ready to sew this sucker up. I'm going to add a keyhole with a button closure at the back neck - totally unnecessary as it fits over my head as is, but it'll "add interest". Coming right up...
