Whether Classic or Casual, Royal Engagement Portraits Are Always Dreamy

The young Princess Elizabeth first met Prince Philip in 1939, when she was 13 and he was 18. It was years before they started dating, and although they got engaged in 1946, Elizabeth's parents insisted on not making the news official until after her 21st birthday in April 1947. Elizabeth and Philip's engagement was announced three months later, and they were married four months after that. Four children and 70 years of marriage later, they will celebrate their platinum wedding anniversary on Nov. 20.

Princess Elizabeth and Prince Philip's engagement was marked with formal portraits taken at Buckingham Palace that included her parents and sister Princess Margaret.

Thirteen years after her sister's engagement, Princess Margaret accepted a proposal herself. She and her photographer Antony had been in a relationship that was not public knowledge, and so the news of their engagement was something of a surprise to many. The couple married three months later, and they had two children, but divorced in 1978.

Official engagement portraits of the couple at Princess Margaret's family home, Royal Lodge, were released.

The couple first met in September 1972 and got engaged eight months later. They married six months after that in November 1973 in Westminster Abbey and had two children, but divorced in 1992.

The princess and the army captain chose a meadow for their official engagement picture, creating romantic photo goals forever.

Charles and Diana had only been together for around six months before he proposed. They were married five months later, just four weeks after Diana's 20th birthday, and became parents to Prince William and Prince Harry. They divorced in 1996.

Andrew and Sarah got engaged after a yearlong relationship and married four months later. After becoming parents to daughters Beatrice and Eugenie, their marriage ended in divorce in 1996.

After a longer courtship than his elder siblings had with their partners, the queen's fourth child has got his happy-ever-after with the the woman he married. Edward and Sophie first met in 1993 and didn't get engaged until six years later. They married five months after the announcement, and after having two kids, they recently celebrated their 18th wedding anniversary.

After a decades-long on-off love affair, Prince Charles finally announced his engagement to Camilla in 2005, and they were married two months later. They celebrated their 12-year wedding anniversary in 2017.

Times have changed since the starchy and formal royal engagement portraits from previous decades, and Princess Anne's laid-back son Peter and his new fiancé, Autumn, didn't pose for an official portrait. Peter and Autumn instead posed for a casual picture at Gatcombe Horse Trials. They married nine months later, and after two children, they will celebrate their 10-year wedding anniversary in 2018.

These two need no formal introduction! Perhaps trying to learn from the whirlwind courtships and subsequent divorces of his parents, Aunt Anne, and Uncle Andrew, William waited eight years to propose to his university girlfriend, Kate. Five months later, they married and will celebrate their seven-year anniversary in 2018, around the time their third baby is due.

After the hoopla of William's engagement, his cousin Zara announced her own impending marriage just one month later. Although, rather than the couple being suited and booted in the state rooms of St James's Palace, Zara and Mike simply popped into the garden of their home in jeans and hoodies for a quick photo op. The couple had been together for seven years and they married seven months after their engagement was announced. They are now parents to 3-year-old daughter Mia.
