I was wondering why the dark red peasant blouse was pulling from the armholes to the bottom of the yoke. The pull lines are represented by the red lines in the drawing:
It turns out that I started the gathers or tucks too far from the armhole edge and had them more bunched up in the center. Here’s the measurement I figured out for the distance from the armhole edge for the first tuck for a size medium (bust about 36″) . The rest of the tucks are evenly spaced with a larger untucked area at center front.
I think this caused a problem because I have cut the top down a lot to be slimmer fitting as my daughter requested. This just goes to show that no matter how long you have been sewing, a creative person will always find new mistakes to make.
I ripped out the topstitching and yoke seam, resituated the tucks, stitched it back up, and now the problem is solved. Gee, I made that repair sound lots easier than it was.
