Crown Princess Mary led the Danish royals as they rounded off a day of birthday celebrations for Queen Margrethe II on Wednesday. Joined by the monarch herself, consort Prince Henrik, Prince Frederik, Prince Joachim and Princess Marie, Tasmania-born Mary attended a glamorous concert in the coastal city of Aarhus.
The elegant 43-year-old sported a stunning midnight blue velvet gown and carried a matching clutch bag, accessorising her outfit with a pair of dazzling earrings and a statement necklace.

While the festivities were in celebration of Queen Margrethe reaching the milestone age of 75, the evening was as much about future generations of the Danish royal family. Mary and Frederik's eldest children, including future king Prince Christian, walked the red carpet with their parents, as did Prince Joachim's eldest sons Prince Nikolai and Prince Felix.
Holding on to her mum's hand, seven-year-old Princess Isabella showed off a sweet pink sleeveless dress, which she teamed with black tights and patent shoes. The youngster's elder brother Christian, nine, looked smart in a navy suit and polished black shoes that matched his father's.

Nikolai, 15, and Felix, 12, also looked dapper. While the boys arrived at the soiree with their father Joachim and his second wife Princess Marie, their Hong Kong-born mother Alexandra, Countess of Frederiksborg, was also in attendance.
Showing that family relations are better than ever ten years after Joachim and Alexandra's divorce, the Countess was accompanied by her second husband Martin Jørgensen.

Earlier, Margrethe's special day had been honoured with suitable pomp.
The monarch, who has been on the Danish throne for 43 years, arrived at the town hall in a horse-drawn carriage following a parade through the streets of Aarhus.
Joined by her husband, sons and their respective spouses, Margrethe waved to crowds of well-wishers from the building's balcony.
