2013 saw the enthronement of two new queens in Europe. As Crown Princesses, Máxima and Mathilde wore hats on major overseas tours and at big events at home; most of their lower profile, day-to-day domestic engagements were completed without hats. This changed with the beginning of their reigns as queen.
2013 Royal Hat Trend #2- The Young Queens Wearing More Hats
After acceding the thrones of the Netherlands and Belgium, it seemed that the first order of business for both Queen Máxima and Queen Mathilde was to order a wardrobe of new hats. Both queens adopted a more traditional approach to hat wearing this year- an approach that saw them add hats for many of their regular day-to-day engagements. While this queenly approach to hats was traditional, the hats themselves (all but one, top row right, the work of Belgian milliner Fabienne Delvigne) were decidedly modern.

Royal Hats 
I hope they continue wearing lots of hats in 2014. It is so nice to see the younger queens carrying on this tradition.
Both Queen Mathilde and Queen Maxima make bold choices. In my opinion some are good and some are hideous. On Maxima, I prefer the beige wool calot she wore during the 200th Anniversary of the Kingdom of the Netherlands celebration. On Mathilde, the hat I like best is the red/orange picture hat with the square crown. I do not like the black donut worn by Maxima in the bottom row or the floppy gardening hat worn by Mathilde also in the bottom row (and Mathilde…those earrings have got to go!)
