One who's beauty is not only skin deep. A girl or a woman who is as beautiful on the inside as the outside. Sometimes it is the inside beauty that makes the outward girl a beauty:)
I met a young newlywed couple recently, and it was her personality and her sweet voice that made her so pretty. She was a person, you understood, what her husband saw in her. He met her by words only, at first, then later got to see what she looked like.
So glad looks aren't everything:) Especially when we get old!
