I bought this for when my grandchild came home. I measured it with a tape measure, and the head circumference was 38 centimeters. It's stretchy and will expand, so it seems like it can be worn for a long time, up to around 2 years old. The sheep's face is embroidered on it, and it's super cute! My grandchild only wore it a few times when they came home in the winter, so it's in good condition. Color: White
