I am quite please with how my blouse came out, even with the wonky neckline. I thank you all for your suggestions on how to make a better knit neckline, and will be practicing these methods.
I decided I didn't want my neckline as wide as the original.
I used McCalls 6886 for the body and sleeves. Instead of contouring as the pattern piece is constructed I boxed it and took out the contour. The neckline, cuffs, and waistband was made of Ponte Roma Knit. In hindsight, I should have used a not so tightly woven knit.
