This is my thought after looking at several of MM's threads here in the Royal House of Fashion: she is a gorgeous woman, a true example of the stereotypical Scandinavian beauty, but she just does not photograph that well.
When the photos are good, she's stunning, but so often, they are awkward, bug-eyed, have an odd head tilt, or something. Don't get me wrong, I really think she's lovely- I mean, if you watch some of the videos of her, she is always pretty and fresh. And she's especially lovely when looking smiling at Haakon or watching her three children- she has so much love for them.
