My last sloper had too much crotch in the front. You can see here when I bend forward slightly....yuck!
Here it is with the excess pinned out.
Now with the excess pinned out I remeasured my crotch length using the bottom of the waistband to locate my waist. Whooa! 25.5! That's a long way from the 28" I used in my first sloper. I remeasured the crotch length while wearing my first sloper and I got 27" because of all the extra fabric. Here is the third sloper with the new crotch length. Much better!
