Queen Elizabeth II, Princess Diana and Kate Middleton are pretty in red.

Photos of the Queen, Princess of Wales and Duchess of Cambridge wearing tiaras and red gowns were shared on Instagram. In the snaps, the three royals look very elegant and sophisticated.

“Gorgeous classy classic beauties in red,” one netizen wrote.

“Princess Diana the best,” a different user commented.

A number also praised Middleton, saying that she has a “lightweight personality.” Another said that the future queen is gorgeous.

Middleton’s photo was taken during a state banquet at Buckingham Palace. She is wearing the Lotus Flower tiara and a Jenny Packham gown in her photo. She tied her hair in a stunning updo, as well.

Princess Diana’s photo was taken in March 1983 during a state reception in Hobart, Tasmania. The princess is wearing a floor-length red gown and she paired it with a Spencer tiara. Meanwhile, the Queen is as gorgeous as Middleton and Princess Diana in her red outfit and tiara.

The Duchess of Cambridge will be wearing a tiara again on June 3 for a state banquet at Buckingham Palace for Donald Trump’s official visit to the UK. The Queen will also be there since she will be hosting a private lunch on the day for the U.S. President and the First Lady, Melania Trump.

Donald and Melania will also join Prince Charles and Camilla for tea at Clarence House. Prince Harry will be joining the royal family for the private lunch but not his wife, Meghan Markle.

In related news, Middleton reportedly wants another baby girl for their family. One insider said that the duchess loves Prince George and Princess Charlotte’s bond and wants Prince Louis to have a sister close to his age, too.

Another source said that Middleton wants another girl for Princess Charlotte. Prince William and Middleton’s only daughter has positive effects on big brother, Prince George, and Prince William knows the benefits a second daughter might bring into their growing family.

Betting odds suggest that the Duke and Duchess of Cambridge will be welcoming a new baby next year. Many believe that the announcement is happening sooner than later.
