I think what I was trying to say is that she would like to be all things to all people. The super focused business woman, the Feminist fighting for woman's rights, the present Mum who has time to make lunch with love notes, nature lover and gardener, cook, beauty and fashion icon, girl next door who makes her own Christmas decorations, jet setting philanthropist. So many identities you could pick one to go with. So yes, character was the wrong word.
Physically I think personally she is very attractive in a way that her face can be used to portray each of these different identities at will. Some people will only look one way, some will be beautiful but homely, some beautiful and powerful, some beautiful and sexy. Meghan's face is the kind that can wear different looks, so she makes an excellent model. A face that is striking and somehow forgettable if that makes sense.
Of course if you are buying in a personality not a face to front your brand then it may need a specific identity rather than lots of confused ones.
