15-year-old daughter feels embarrassed by her mother's simple dress, and her mother is very sad. How to guide her correctly?

Don't try to change your child's mind. Anyone who tries to forcibly change other people's minds will eventually lose both sides. To educate children, we must be quiet and thoughtful. If you want your children to read more, you should read more yourself. If you want your child not to be vain, you can't be vain yourself. I don't think it's necessary to wear simple clothes without temperament, just wear rags. A good eye can also buy cheap and beautiful clothes. I think my daughter thinks her mother is not simple. Maybe her mother is content with the status quo and doesn't work hard to make progress, which makes her feel desperate.
