Princess Maxima looked gorgeous in an elegant fuchsia gown as she supported her mother-in-law Queen Beatrix on the balcony of Noordeinde Palace, to greet well-wishers gathered on the streets below.
The royal party, which also included Maxima's husband Crown Prince Willem-Alexander, his brother Constantijn and wife Laurentien as well as Beatrix's sister Margriet and her husband Pieter van Vollenhoven had toured the city in an exquisite horse-drown carriage.
Dressed in all their finery, the group had stopped off at Ridderzaal - or Knight's Hall - for the official opening of the country's parliament.
Though they appeared happy and relaxed as they took part in the glittering proceedings, the family are still coping with a difficult situation behind the scenes.
The queen's middle son Johan Friso, 43, has been in a coma following a skiing accident. He is now receiving specialist care in a top London clinic.
