Foolishly, I decided to make this dress without sewing a muslin first. I should have made a muslin version first because then I would have remembered these hips and the fact that there might not be enough ease in that area. This is a tough lesson for me to learn. I just wanted to sew.
Luckily, I was able to remove the stitching and replace it with the narrowest seam allowance possible on the back, side and front seams. It worked. And that was a close call.
