|Tessa on the Web created several guide sheets to help people using the Dress Shop pattern drafting software. I do not have this software, but I find her fitting guides very useful and convenient for commercial pattern adjustments and self drafted patterns.
1. Sloper Fitting Corrections shows line drawings of the wrinkles, the 1-3 things it could be. Then, how to decide which of the 1-3 things is the cause and what is the specific fix.
2. Pant measurements helps you see what each seam does and where you might need an adjustment.
3. Custom Crotch Formula will help you understand why you add to the crotch extension points and how much you might need.
