Knitted with acrylic yarn. It's a navy beret! The head circumference is about 51cm, and it has some stretch. The child in the photo also has a head circumference of about 51cm, and it looks cute whether worn deep or shallow (❁´◡`❁) The shape is relaxed. As it's handmade, I appreciate your understanding (*v.v) #handmade #beret #kids #hat
