Here is the fifth muslin for my greaser jeans. It appears I have resolved the baggy crotch. All I had to do was decrease the back crotch extention. The point that sticks out on the back piece - take it in a bit, following the crotch line, and then taper and blend into the existing in-seam. Make sense?
Now I would love to make these up right away. But the holidays are approaching and I have a few christmas gifts I need to sew first.
