This is the perfect hat for those of us who want to keep our hair up but also want to be warm and fashionable. This fabulous hat come with a large hole in the top so you can pull your bun or tail out it! It is made with a soft fluffy yarn that doesn't itch! I love mine as you can see. More colors will be available soon. But as always if you don't see the color you want, contact me for a custom order!
