I've just finished the best fitting trousers I've ever made [or worn!!].
I owe it all to three things
1. Sure-fit Designs pants sloper made to my measurements
2. Making several pairs already where I've noted different issues that need to change plus I made a muslin.
3. Hints and tips from 'Pants for Real People' by Patti Palmer and Marta Alto. This book was great and could possibly have made some of my previous pairs less issue ridden. I especially liked fitting the trousers [pants] before attaching the waistband then marking the seam lines on both as well as the desired actual waistline. This certainly put the waistband in the correct place at last!!!
Here are the photos during construction.
Have you struggled to get the right fit for trousers?
