The sash is a different fabric and pattern piece. The sash is just fine in terms of body circumference. T
he bodice, sash and torso all connect at the same seam.
My problem is from neckline to sash is too short as increasing the bodice pattern piece added circumference, but not length. The shoulder to neckline is perfect, and then the bodice-to-sash seam is half way down my actual bust. I need to add 3-4 inches in length, to the actual bodice piece so the sash is sitting against my rib cage.
