This is the first Cute Skirt I made.
The one I said was poofy in the back. I thought about reworking the skirt by ripping out all those stitched and zig zagged seams, But the thought of all that ripping and reworking waistbands was more work than I wanted to do. So I ripped open the casing in the back, leaving it sewn to the skirt. Pulled the elastic out of the way and just restitched the 4 back seams starting about a foot below the waist tapering in until the seams were about 1/4" smaller at the waistband. Then I just continued sewing through the waistband fabric to decrease its length as well. You can not even see it in the gathers. I pinned the waistband back in place then while stretching out the elastic, sewed the casing closed.
Now I have 2 cute Cute Skirts.
