Princess Beatrix of the Netherlands arriving at the thank you gala held in her honour in Rotterdam
The big thank you was originally scheduled for September 2013 but was postponed following the death of Beatrix's second son, Johan Friso, in August. Beatrix has been wearing grey, mauve and purple a lot in recent times, the colours traditionally chosen for the next stage after the full mourning of black. Friso's widow, Mabel, is still wearing black for her formal appearances. Queen Maxima chose a regal blue for the thank you gala.

But the evening itself was one of celebration. While the TV programme featured some of the serious side of Beatrix's reign, the big gala was filled with fun and included the sight of the former queen bouncing balloons - and not doing too bad a job of it. There were lots of laughs and smiles too - the perfect way to say thank you to a queen who brought a lot of happiness with her.
