During her down time at home, the Queen keeps it simple but sweet in a blush cardigan and tweed skirt pictured here earlier this year with Princess Anne at Windsor Castle.

It’s not all about solid colours when it comes to dressing the Queen. Here, she wore a flower-print shift dress to meet with the winners of the 2016 Queen’s Awards for Enterprise at Buckingham Palace.

Never one to shy away from colour, the Queen donned a yellow coat and skirt ensemble with a matching hat, at the Palace of Holyroodhouse’s Investiture and Garden Party in Scotland.

The Queen looked ravishing in red when she received a personal tour of the RAF Valley base from the Duke of Cambridge, Prince William. The Duke was stationed here as a rescue helicopter pilot in 2011.

The Queen wore green on her birthday this year and along with The Duke of Edinburgh and other members of their family, watched a magnificent flypast by the RAF from the balcony of Buckingham Palace.

We couldn’t resist adding in this photo of the Queen enjoying a walk around the annual Chelsea flower show. Her outfits tend to match the colours of the flower seen here don’t you think?

While we love seeing Queen Elizabeth at public appearances in her brightly coloured outfits, we love it more when she hosts official royal events. She was practically dripping in diamonds as she delivered the Queens Speech during the State Opening of UK Parliament, in the House of Lords at the Palace of Westminster in London.

See here for a close-up of the crown she’s wearing:

Pretty in pink, Queen Elizabeth showed off her girly side in this deep rose-hued coat while meeting guests as she hosted a Garden Party at Buckingham Palace.

The Queen once again does casual chic in a tweed skirt and blush twinset as she’s surrounded by her two youngest grandchildren and her five great-grandchildren in this photograph taken at Windsor Castle just after Easter by renowned portrait photographer Annie Leibovitz.

This photograph was taken at Buckingham Palace in July in The Queen’s private audience room. Her Majesty is seated at her desk, with one of her official red boxes wearing another pink-toned floral shift dress.

Looking every inch the royal that she is, The Queen wears the traditional Order of the Thistle robes as she enters St Giles’ Cathedral on the Royal Mile in Edinburgh for the annual Thistle Service in Scotland.
