|I have very large hips and find that elastic waists have too much ease in them. I pinched out two darts on each side of the back and one on the fronts, marked them and sewed them, keeping the last two inches straight up rather than at an angle. I added the zip and sewed the side seams. To do the waist I stitched 1" elastic to the serged top edge , stretching as I went. The elastic was cut 1" smaller than my waist. Once sewn on, I folded the waist over and stitched vertically at the sipper, darts, CB and side seams. They don't look as "elastic-y" this way.
