Great pattern, with a lot of possibilities for variations. I am sure, I will make another one (or two, or three:)
The fit is perfect and comfortable to wear.

I decided to skip the lower part as it’s not flattering for my body type.

My modifications:

1. Made body longer to compensate lack of lower band. CO 70 stchs for the sides instead of 31 stchs for size 4

2. Used waste yarn and cable cast on for the sides

3. Side seams made with 3 needles bind off on the wrong side.

4. Connected pieces with 3 needles bind off on the right side.

5. Finished with 2 stchs i-cord for the bottom (If I think ahead, I would just incorporate it with sides, instead of doing it afterwards)
