The Queen was dressed in a vibrant blue dress as she hosted a garden party at Buckingham Palace

Queen Elizabeth II made an appearance at a garden party held at Buckingham Palace wearing a vibrant blue ensemble.

The monarch, who celebrated her 92nd birthday on April 21, appeared to be in good spirits as she enjoyed the sunny weather in the company of Prince William and Princess Eugenie.

According to the photos posted on the Royal Family's official Twitter page, the Queen matched the dress with a hat with peacock feathers, white gloves and a pearl necklace.

Princess Eugenie was as cheerful as the Queen but opted for a navy dress, which she complemented with a very peculiar hat that had the word 'love' in it.

It isn't certain, but the hat worn by the Princess might be a representation of the current happy phase of her life. According to her father, Prince Andrew, she is set to marry Jack Brooksbank on October 12, 2018.

Eugenie admitted that, even though the couple has been together for seven years, she didn't expect to be proposed to during heir trip to Nicaragua in January.

The Duke and Duchess of Gloucester, as well as the Duke of Kent and Princess Alexandra, were also spotted mingling with some of the 8000 guests invited to the party.

The Band of the Household Cavalry and the Band of Royal Logistic Corps provided the entertainment as people chatted among themselves and explored the beautiful flora of Buckingham Palace.

This was quite a busy week for Queen Elizabeth, who welcomed George Brandis, the Australian Commissioner to the United Kingdon, on Wednesday, May 30.

During the private audience at the Palace, several photos were taken of the two figures, but one detail popped out: a framed picture of Prince Harry and Meghan Markle that had never been seen by the public before.

The photo is believed to have been taken by Alexi Lubomirski, the photographer responsible for the Duke and Duchess of Sussex's engagement shoot.
