I bought this a few years ago and wore it. My child used it when they were 2 years old, but I think they can still wear it at 3. It's very cute and can be worn by any gender. Two types of yarn are used. 100% Rayon 70% Cotton 25% Acrylic 5% Nylon Please understand that this is a used item worn by a child, and consider it after carefully checking the images.
