BOBO CHOSES knitwear. Size is unknown, but likely for 1-2 year olds. I'm selling it at a low price because I'm unsure of the size. 100% acrylic Used only a few times. There is some pilling. Also, due to overseas manufacturing, there are some imperfections in the sewing, such as buttonholes. Please refrain from purchasing if you are sensitive to used items.
