I can sort of see my usual hip forward slouch just looking at the altered pattern.
Based on your comments (Thank you again for the help!) I took an inch slice out across the back and side. Here it is marked.
The back section was cut out and the pieces taped together. Then I cut the side piece to the front seam.
And blended the seam line using the hip curve.
After I did this I decided 1 inch probably was not enough and took another 1/2 inch out of both pieces, and finally an extra 1/4 inch off the back. Please let this version fit better.
