My alterations:

• Made a V-neck by ignoring the shaping for the rounding of the neck and increasing near the front edges below the mesh until I had the right stitch count at the front.
• Knit size 48 at the top, then made A-line shaping to my measurements by increasing at four points around the body starting about 1” below bust shaping.
• Faux seams by slipping stitches on the right side for one column each side.
• Switched 1x1 hem ribbing to 3x1, which I just like better!
• Modified button band to be in one piece (matching the V-neck shaping) and did a few extra rows, which looked more balanced for my larger size.

LOVE THIS THING. Really good fit, excellently light but warm yarn, I think I’ll be getting a lot of wear out of it.
