The Queen and the Duchess of Edinburgh have stepped out looking supremely elegant in matching blue ensembles.

Both Camilla, 76, and Sophie, 59, selected stylish pastel dresses for a garden party at King Charles’s official Scottish residence, the Palace of Holyroodhouse today. Also joining them at the event was the Duke of Edinburgh, 60.

The wife of Prince Edward has stepped up her royal duties since the King’s coronation, a year ago – particularly recently, after she took on engagements on behalf of the cancer-stricken monarch amid his treatment.

While Her Majesty opted for a stunning long sleeve frock with a lengthy floral pattern at its centre and white leather gloves, the Duchess donned a similar, yet simpler dress decorated only by a large bow placed at the shoulder.

The colours may be a stylish coincidence, or may also signal a possible nod to the nation’s flag colours.

Camilla’s Fiona Clare dress was adorned with intricate trim detailing, and accessorised with a glimmering brooch.

But Sophie wore more understated maxi-dress, featuring additional fabric at the left shoulder, which cinched at the waist.

Both royals also sported similar hats, however the Queen’s Philip Treacy number featured a large blue rose while Sophie’s fascinator was beautified with three feathers.

The pair even opted for the same coloured heels – a pair of nude pumps, Camilla’s shoes differing slightly due to a black pattern at the toe.

While Camilla wore her hair down, Sophie gathered her blonde tresses back – but both went for glamorous, summer evening make-up looks.

The women appeared in high spirits and were photographed greeting various guests in attendance.

King Charles was also on fine form at the garden party today and even asked to stay later than planned order to meet as many people as possible.

His Majesty, accompanied by the Queen and the Duke and Duchess of Edinburgh, greeted hundreds of the 8,000 guests gathered at the Palace of Holyroodhouse, his official Scottish residence.
