I find Charlotte to be a very beautiful woman, moreso even than her mother and her grandmother. It just seems like she won the ultimate gene lottery but, that is not to say that that in itself would do it. She is educated, sophisticated, and has a healthy approach to life.
As a young child she was a beauty and all the way through to adulthood the paparazzi have tracked her life. But unlike many others of similar situation I think the lessons her mother taught her when she was very young have served her well. There has been not rebellion, drugs, scandals (except those created to sell magazines) and her partner is a man of substance not superficiallity.
She lives life on her own terms and seems well able to tell what will look great on her as well as what she can make look great. Sandals to stillettos, she covers every occasion with ease and I don't see her wearing some of the nightmarish ensembles her mother trots around in just because her favourite designer produced it.
