A pink swim cap featuring flowers and frills, with a comfortable one-size-fits-all fit. We used this for water play from around age 2 until the eldest year of kindergarten. As it says "one size fits all," it truly is one size fits all! The entire cap may be faded, but there are no uneven color patches, so it might not be too noticeable. The fact that there are no loose threads at all is just like Mikihouse. The circumference of the brim of the hat itself (inside) measured 45cm. So, it likely means it can be worn from 46cm and up. Looking at photos from kindergarten, the swim cap with frills makes the wearer look cute. Mikihouse - Color: Pink - Size: Free (46-54) Thank you for looking.
