You can observe the style of her previous hair band first. If she has dark hair, she can choose a slightly brighter hairband, the bow or rabbit ear that is very popular now, the simple and refreshing one, the blue or dark red one, which is low-key but not like hair color. I suggest you go to Kawaii or Sanfu, or you can take her directly to let her choose. The picture shows my own headrope now, you can refer to it.
