This lovely top is so easy to knit. The design is simple enough that it will look as good with shorts and jeans as it will with a dressy skirt; or wear it to work, layered under a jacket. It has shaping that hugs your waist nicely, but it's roomy enough that it won't cling to your hips. If you prefer a slightly looser fit, you might want to consider working the next larger size.
The yarn I used works up at a gauge of 5.75 sts per inch in Stockinette stitch; if you wish to use a different yarn, make sure you find one that will match this gauge.
23 sts and 32 rows = 4" (10 cm) in Stockinette stitch
