This is a really nice easy and pretty pattern that’s fun to crochet. Mine has a few changes from the original: I did chainless starting stitches, because I like row edges to be squared off and more substantial than chains. I shaped the sleeves to taper from 7 inches at shoulder to 4 inches at wrist, and didn’t do any sleeve edging. I did the simple sc edging on neck and hem.

A comment about the written pattern (I used the free version): Some of it isn’t standard or customary, but it’s understandable anyway. Example: “sc around the middle of the next ch 3 group” is typically written “sc in next ch-3 space”.
