You did the fitting,
you made the adjustments to your pattern
When you walk your inseam, the front and back don’t match up!
Here are 2 ways you can make an adjustment to TRUE up your pattern.
This is shown by having to make the back pant 3/4” shorter than the front, 💙
But do keep mind, you can change the amount of difference or do this adjustment on the front if that is what you need in your case.
Also, the second example will alter your crotch curve. You may want to adjust that after to make sure it is what you need there.
