Finished a couple days ago... a simple set of accessories, but fine for the application! The ears have cardstock in them and are attached to a headband. The arm things have a bit of elastic at the top to help keep them up. I left the tail unstuffed since she will be sitting on it. It is attached to the jeans with a small elastic strap around the belt loop. If anyone pulls it, or she gets it caught, it will stretch before breaking off. I made the shirt out of the only gray stretchy fabric I had on hand.
