The stitch pattern hints of "crochet," but it isn't. It is a simple, four-row/round repeat. Plus, the vest is knit from the top down, and in the round, so there are no seams. There aren't even any seams on the tops of the shoulders!
Fad-Classic is perfect for an intermediate knitter. If you're an adventurous beginner who knows how to knit in the round and follow and incorporate a stitch pattern, go for it.
