The color is navy (with a mix of white threads). Head circumference: approximately 40cm Depth: 12cm (excluding the pointed part) Since it's loosely knitted, it should be fine even if the head circumference is slightly larger. It's designed to be worn above the ears, with the ears exposed, so it's shallow. Each item is made with care, but as it is a handmade product, please refrain from purchasing if you are concerned about variations in the knit. m(_ _)m
