This is a cardigan as well, but that’s arguing about the use of a word.
To us knitters and crocheters, a cardigan is a sweater that fastens (or not) in the front, or to the side. It’s a blanket term.
Also, yes, my sweater does have a kangaroo pocket in the front. (As does the one on that webpage I put in my previous answer.) I’ve also knit this cardigan, but that one doesn’t have pockets.
I know you speak disparagingly of argyles, but this vest is pretty d*** awesome. (So is the scarf on the front of this book.)
P.S., the dictionary says it’s “a knitted sweater fastening down the front, typically with long sleeves.”
I’m not trying to pick a fight, just pointing out that there are some awesome cardigans out there.
