I chopped the skirt off after removing the ruffles that were in the way, and I took up the shoulder a few inches to fix the gaping armholes. And my new tank top is just perfect! ...or will be when it's warm enough to wear a tank top.
And with the leftover skirt part, I cut strips and stretched them out to make a scarf necklace. I used the bits cut from the shoulder straps to encase the ends of my strips.
