Fuzzy Sheep-Like Vest - Reversible

This cute vest is fuzzy on one side and has a soft cotton blend taupe material on the other side. Pockets on both sides, and there is no tag so it is reversible. I've never worn it, but I bought it from a thrift store, so it's not new. I'm a size 8 and it fits and I can zip it up, but there's no tag. I would say it's a medium, but I'm guessing.
