It seems like lately everything is called poncho or kimono. I don't see how this is anything but a vest. Certainly a long, cozy one, and one with shoulders that drop down low, but a vest nonetheless. A sweater with no sleeves, and an opening in the front.
The pattern I originally purchased for this yarn did not work out, so I had this lovely alpaca and no plan, but not enough yarn for something with sleeves. I made this simple sweater with the intention that it can be thrown over the top of outfits for extra warmth during the coming chilly months.
At the last minute, I made a belt with the extra yarn. It took longer than planned because it needed some fabric on the back to add strength and stability, but I think it was the right move.
