☆ Only tried on ☆ Head circumference approximately 44 cm, height approximately 24.25 cm excluding the pom-pom. I measured the inside of the knit hat, the bottom part, as a rough measurement. It's a stretchy knit material, so I think it will fit anyone with a normal head size. Please note that this item is stored at home and has been inspected by an amateur, so there may be occasional oversights. Thank you for your understanding.
