This pretty pink hat is sized for a child or pre-teen. It has a 20" circumference, and is 5.5" in length (from the crown to the rim). It is made with a very soft, stretchy and durable Italian-made silk yarn. This is going to be a one-of-a-kind item for my shop. This is a lovely, fun hat. But I had a lot of difficulty with the sizing. I will consider a custom order for a specific size and/or color.
