In perfect harmony

The start of the Dutch State Visit to Denmark began with lots of smiles and hugs. And it didn't take the sharpest eye to see that the kings, queen, princes and princesses involved in the event were rather in tune when it came to selecting outfits. From the muted greys and beiges on display at the official welcome to the symphony of blues and whites that made the gala dinner truly glitter, everyone matched. But today things went one step further. As Queen Maxima and Crown Princess Mary stepped out for a visit to Samso, these two royal women were rocking one regal look.

The Queen of the Netherlands chose a fitted beige coat with snakeskin shoes and a rather fetching trilby hat. Meanwhile, the Crown Princess of Denmark chose a pale grey coat with beige boots and a rather matching trilby hat. It was a shame that Princess Marie wasn't able to come along - she'd already got the trilby trend going by donning one at the airport for the official welcome for the Dutch royals on day one of the State Visit. But then hers was very dark whereas the royal ladies today both went for pale brown or beige. And the effect was striking.

The royals were on Samso to learn more about green energy and sustainability - themes that the two couples have shown a deep interest in over the years. Samso is a carbon neutral island and its royal visitors were shown the Energy Academy and enjoyed a lunch made form local ingredients.

The colour co-ordination continued in the evening when King Willem-Alexander and Queen Maxima held a reception for their royal hosts. The event included a display of contemporary dance. And the two queens, Margrethe and Maxima, were perfectly co-ordinated in orange and peach while the two princess, Mary and Marie, went for black to complete the matching theme of the visit.
