What is an ideal beauty?

In my opinion, ideal beauty is not only about appearance. It's about interior beauty, a beautiful soul and a responsive heart. If a person is ready to do anything for others, to help in any situation, to give the most precious things and not to think about their gratitude, then that is a really beautiful person. If there were more of these kinds of people on the earth our world would change for the better and there wouldn't be room for for evil, fighting, killing or wars.
The person in whose heart lives cruelty, jealousy, meanness, greed or hypocrisy can`t be beautiful. All of these qualities certainly impose its mark even on the most perfect face.
And on the other hand, even the most modest, nondescript person who might not have great physical beauty, but is endowed with spiritual beauty, is, no doubt, beautiful.
I guess that real beauty is a harmony of different features of a person. But for example, for one person the most important thing in people is appearance, for another one, clothes and other people pay attention to the beauty that lies inside. The beauty that is in everything, in a person's eyes, actions and words. It's just important to notice it and even better if the person is harmonious (?). But that doesn't happen so often.
