Here are some suggestions for you, I hope they will be helpful to you:
1. Maybe she has had many dolls to accompany her since she was a child, so you might as well give her another one this time. Girls always hope to be a child in the eyes of others.
2. You can also buy her a creative cup, which is a very practical and representative gift.
3. See if she has any favorite stars, etc., and you can give her related gifts. She will like it very much.
4. You can give her a book. She is still in school now! Giving her a book is also very suitable.
5. You can give her small gifts such as key chains, bracelets, necklaces, crystal balls, etc.
6. Or you can DIY a gift for her. For example, it can be made of some small things. There are also some fabrics. They are all good
The crystal piano mentioned above is available in many gift shops or gift websites, and some are also customized.
