I selected McCall's 2818, a Palmer/Pletsch, Classic Fit Pattern. My fabric is metallized quilting cotton purchased at Joann. I was hoping to end up with a wearable muslin. I selected my pattern size, 12, based on my high bust. After tissue fitting, I lowered the bust apex by 1" as always and cut my fabric. I encountered some difficulty during assembly easing the princess seams; there seemed to be quite a lot of fabric to ease. I'm surmising that the metallic finish on the cotton was the cause of the problem.
Being spatially challenged, I had no idea how the fabric I had pinned out of my top related to the flat pattern pieces so I decided to follow an excellent piece of advice from Belinda at PatternReview.com.
"Let the toile tell you how, what and where to alter."
There are still issues. First, my alteration radically changed the shape of the arm scye. I don't think I can alter my facings to match so I'm going to have to finish them with bias binding instead. Since the armhold facing was integrated with the neck facing, well, yeah...that's getting the bias binding treatment, too. Also, the upper chest is still just a tad too wide and I'm not sure how I'm going to fix that yet. I might just try a small, inverted box pleat at the center neckline edge. Not sure.
