I played with it a little, pin it in various ways and the most favourable solution was this one with the two overlapping 'pleats'. Then I made two darts behind because it was still big and I added a zipper.
If you remember this dress then you know that when I got my scissors near it a large piece of fabric was left.
I also used the flower(pin) which I plan to make a necklace with, but used it as a brooch for the photo shoot.
Are you happy now mom?
