Here is my latest top experiment. McCall's 6241.
Some notes on the top:
I made View A, the short sleeve version. As you can see in the picture below, I drafted an attached facing to flip under so I would not have to narrow hem the cheap jersey. This facing worked GREAT and the neckline stays perfect all day long. For the back neckline, I removed some of the seam allowance and drafted a binding that I just serged on, then topstitched. It was a great solution to the narrow hem problem.
