For the back I used McCalls 7506. Hollys dress had a waist in front and back.I made a very long split in the back. My fabric was a polyester crepe from my forgotten fabric stash😌.The dress is also fully lined, also from stash.
I had the trim in my stash as well. I purchased it while I was in living in NY years ago. I didn't know what I would use it for at the time. But I had to have it.You know how that is.
