So here it is!
Pay no attention to the monkey modelling the cowl, please. And yes, she in fact does have a chin in real life, but it was camerashy.
As you can see, it has three buttons on the front to fasten it on one side, and a single button on the inside of the other end to keep that end up. In other words: it can go as loose or tight as you want. I gave it a bit of texture by adding something slightly resembling cables, but I think I'll have to recheck how to work cables in a crochet piece because they went diagonally instead of just straight from one side to the other. Oh well.
It's really cozy, nice and warm, and my coworker/crochet guru complimented me on how well it was made. So wooh!
