How popular is Princess Mette-Marit? I ask because I do not think she is beautiful but she still seems to be well loved in her country.
Diana was never all that, I think the only reason people started to believe she was is that a) Charles was so much older and he, unfortunately, had a stereotypical British look about him. b) she was young c) Those around her when she married were quite old at the time, Elizabeth, Margaret, Philip, Anne, The Queen mother....any looks they may have once had had faded.
Arguably the most beautiful woman in the modern BRF was Princess Margaret, but despite her looks I think there did come a time when she was not so popular because of her behavior and attitude towards others.
