Thanks Fran - definitely no elasticated waists. The Cadence I think I actually have, and I guess I could add a gathered skirt to the top part. The first Lekala was the closest I could find, although I'm not terribly keen on princess seams. I'm not sure how I missed the second Lekala, because that is pretty close to what I'm after - I may need to raise the waist a little, but that shouldn't be a problem.
Lots to work on there!
