At the HC Andersen gala she was wearing this
piece of horror, so I believe you mixed it up with the gala that she visited with CP Mary.
I agree that she seems to be a very nice person, always radiant etc. But I can not recall any royal lady who has worn more ghasly clothes than Laurentien. Anyway, there is a thread tom discuss more about Laurentiens style, which can be found here
And I agree with Mandrake, the changing of her first name seems rather odd to me too, though Princess Marijke did the same and Mabel Wisse-Smit ditched the last name of her deceased father and took the surname of her stephfather. Marijke changed her name as she thought it sounded to childish, but in Laurentiens and Mabels case I suspect some snobbery.
To princess Beagle: I don´t understand your comparison to Martha-Louise of Norway. With Laurentien she is the Princess that has the most unconventional style of dressing, though usually with a much better result than in Laurentiens case. How Laurentien dressing herself a bit less horrid would turn her ´vague´ I fail to understand too. Princess Irene usually dressed impeccably and still talks to trees and dolphins, as does the Prince of Wales.
To Stefanie: I remember an article in a Dutch current events magazine (Elsevier maybe) and apparently in the beginning of her marriage the court adviced her how to dress. I am glad she isn´t listening to them anymore as she looks younger now than when she got engaged.
