Dear Lena & Nadine,
Thank you for fitting comment 1514 size 54-6.
Are you sure you want to change position of back waist lower for all sizes? Because you have released pattern size 36, 42, 48 and other size between these sizes. It means I have to do re-grading.
Regarding center back seam, there is grading jumping between 36-46, 48-54. The grading of big zise is shoter than small size.
(at the moment I could not show nest pattern to you)
May you compare the fitting result of 54-5 and 54-6 again? you did not say anything about waist position on version 54-5...
and if you want to change it, how much do you want to change for 36-4 and 54-6?
