That's really nice. I always mess up basic rectangle skirts because I drastically underestimate how much fabric I need (twice the size of my waist? That's plenty right? ---- Ha.Ha.No.). Is that the problem you had with your previous version?
Also, kudos on the invisible zipper. I was terrified of them for so long but then I watched a tutorial on Burda Style
and facepalmed - Why was I not always doing this?! I recently started and I can say: there is nothing to be afraid of. It's so easy!
