She is petite but always, always, always wears high heels to make herself seem not quite so short.
It is gragic that Letizia is suffering from an eating disorder. I hope she finds the help she needs. It is a serious mental/ emotional illness an should be treated as such. Just because she exists in the public eye, it does not mean that this problem should be ignored. Just like Princess Diana suffered from anorexia and bulimia; it does not look attractive but more importantly, it is a physical manifestation of emotional anguish.
It is wonderful if Letizia truly has a beautiful mind and heart. I don't understand why we have to pretend that every princess is pretty, physically. External beauty is not very important, and since Felipe married Letizia instead of an attractive woman, it shows he his priorities are not about who is good-looking. He searched for other qualities in a wife, and I am proud of him for that. When i think of what qualities make an excellent queen, I think of characteristics like kindness, sound judgement, eloquence, humour, compassion, strong moral fiber and integrity. Being pretty truly does not matter to a princess.
