I've decided that I quite like the outfit Laurentien wore to Prinsjesdag. Whilst it's rather plain in the terms of colour, I think it fits her usual taste because it's rather "prominent" in feel to me. I like the regalness of the dress and I agree with An Ard Ri - she looks like a royal woman from Catherine de Medici's time, or even Catherine herself! I like her dragon fly brooch too. The only thing I don't like about this look is her hat, but generally I'm not really a "hat person" so it can be hard for me to like hats.
I like Laurentien's second outfit. The colours go well together. I particularly like her coat's soft shade of pink, very pretty.
