Fix Deep Creases Under the Backside
This is a pattern correction for people with flat backsides or forward-tilted pelvises. You can get a lot of excess fabric in the back here.
To see if you can correct this area effectively, pin the excess up and then try moving around a little. It might be a little bit of a fisheye shape. If you can move around ok with it pinned, it means you can eliminate that excess.
Draw a line where the fisheye was (across the pattern).
Draw a line from the front rise to the center of the fisheye.
This is a slash-and-close correction. Cut along those lines, pivot, and tilt to close as shown.
