Would you agree if I said that a woman's sweet expression far exceeds her actual beauty?

A middle-aged woman just entered the coffee place. Initially I only looked at her because of her pronounced curves (sorry.. :) but her face was very homely, no make up, curly hair (which normally I am not so drown to) humbly dressed (clogs with sport socks..:) But then after she's been sitting a while across me and talking to a guy friend, her expression is so sweet, so peaceful almost angelic, that she looks so beautiful to me now. Does that ever happen to you, this change of sensation once you get to know someone a little more?
