Found it! "Den Troonrede" is the link to click to see a little clip of Beatrix. I thought Her Majesty was extremely elegant today! The colour really suited her and the hat was fabulous. The outfit was perfect and very very appropriate for Prinsjesdag.
I like Queen Beatrix's dress. The neckline is very flattering. However, I don't care for the color - that exact same dress with just a bit more blue in the color would have been much better in my opinion.
Maxima was created Princess of The Netherlands, Princess of Orange-Nassau, Royal Highness, in her own right, and she is Princess of Orange by virtue of her marriage;
Laurentien was created Princess Laurentien of The Netherlands, Princess of Orange-Nassau, Royal Highness, in her own right;
Mabel is Princess of Orange-Nassau, Royal Highness, by virtue of her marriage.
It will seem as if I absolutely want you te be wrong today, but I read that Laurentien wasn't princess of her own right and so was "Princess Constantijn of the Netherlands", by courtesy "Princess Laurentien".
