Yup, casual outdoor clothing are best outfits of all on Mette-Marit
That is the annoying thing about her - she could look so good if she accepted a bit of advise. Nobody expects her to be a fashion icon, but at times she looks as if she got dressed in the dark and hit the little house wardrobe or other things.
MM looks best when she leans into a sort of California-casual/classic minimalism look. More formally, her outfits for the Nobel ceremony are usually chic. I think she'd prefer to be more boho and high fashion (ruffles, patterns, trims) but those looks aren't always her friend
