Celebrations for Queen Margrethe II's 75th birthday concluded in style on Thursday night. Accompanied by her son Crown Prince Frederik and his wife Crown Princess Mary, as well as a host of European royals, the birthday girl stepped out for a glamorous dinner party and firework display at Fredensborg Castle.
The Danish sovereign, who was unaccompanied by her husband Prince Henrik, sported a long-sleeved powder blue gown accessorised with gold and turquoise jewellery. She was closely followed by her younger sisters Princess Benedikte of Denmark and Queen Anne-Marie of Greece.
Princess Mary looked as elegant as ever in a stunning silver gown and matching heels while Prince Frederik was dapper in a navy blue tuxedo and bow tie.
