Originally designed with no shaping, you can choose to ad subtle or full waist shaping.

Check the Yarn Estimation Chart on the KnitFit website to determine how much yarn you will need for your gauge and size. 

Knit a gauge swatch with 40 stitches and 40 rows in stockinette to get an accurate gauge and check the resulting fabric. Adjust your needle size until you get the feel that you want.
