Little wooden girl or monk or saint or something very cute and odd

I found this funny little, very light wood statue in a thrift shop. She is nailed to a piece of wood. It looks like it might be very old and once had paint. I love the way the robe and hair fall and how smooth the wood is. the face is a different color, which is why I thought it might have been painted. It wasn't until I photographed it that I realized how out of proportion the head is to the body. Any thoughts on what it is?
