This is a knitted hat for children. I received it as a gift, so I don't know where it was purchased. It appears to be a hand-knitted hat. The color, the pom-pom, the button, and the stitching – every detail is stylish, and I loved its cute retro design ´ᴗ` There is no size indication, but measuring around the inside of the brim gives approximately 50cm. For reference, my child has a small head, but they were able to wear it from a very young age up until around 1st or 2nd grade of elementary school.
