Beaming Prince George steals the show as he dons white shirt with tartarn in new royal portrait

Prince George has proved he’s all grown up as he donned his signature style white shirt with blue piping in a new royal portrait released today. 

The little royal, 6, can be seen smiling coyly as he poses alongside the Queen, 93, Prince Charles, 71, and Prince William, 37, in the family photograph of the three heirs released to mark the new decade. 

Prince George wore a smart white long-sleeve shirt with blue piping for the occasion, a style remarkably similar to one he first wore for his first royal heirs portrait in 2015. 

The royal has worn a similar style of shirt on eight occasions in the past few years, including twice for Trooping the Colour, his fifth birthday portrait and Princess Eugenie’s wedding.

The little royal is fast-making the white shirt with the blue piped detailing his signature style, having worn it on more than six other royal occasions. 

He was first snapped in the garment in 2015, when Kate Middleton, 37, photographed him alongside his sister Charlotte, 4, shortly after her birth.

He also regularly worn a similar white shirt with light blue piping for Trooping the Colour, although often opts for a short sleeve version for the summer event.  

The little royal also wore a similar white shirt with velvet navy piping when he was acting as pageboy for Princess Eugenie’s wedding in October 2018.

While the royal’s favourite shirt may be surprisingly similar on each occasion, the little royal proved he is fast growing up by swapping his boyish blue shorts for smart Black Watch tartan trousers for the portrait. 

The slim fit tartan trousers, from luxury children’s brand Trotters, cost £50 and are described as being a ‘smart and festive look for any little boy’ at Christmas.

The royal was first seen wearing long trousers for an official portrait for the Cambridge’s Christmas card in 2018, having rarely worn them publicly, aside from when he acted as a Page Boy for Prince Harry and Princess Eugenie’s weddings. 

Since he’s been old enough to walk, George has worn shorts in all the official portraits taken to mark milestones such as his birthday or the Queen’s 90th birthday.

He’s also been wearing shorts in pictures taken in his school uniform, and when he’s accompanied his parents on overseas tours to Poland, Germany and Canada.

Previously, MailOnline’s etiquette William Hanson told Femail that Kate put her son exclusively in shorts as it’s an aristocratic way to dress.

He claimed that shorts on young boys are, in fact, a silent British class marker and trousers are deemed ‘suburban’, which no self-respecting royal would want to be considered.  

In the photograph, which was taken on December 18, when the Queen hosted the royal family at Buckingham Palace for their annual Christmas lunch, George can be seen smiling coyly alongside his father, grandfather and great grandmother.

The image is only the second time that a portrait of all four royals together has been issued. 

The Queen stands at the front of the picture in a white dress accessorised with a blue brooch and holding one of her iconic handbags.

Meanwhile George and Charles – in a navy pinstripe suit – are stood together on a red-carpeted step.

William stands behind his father, son and grandmother, smiling at the back of the picture in a dark suit and navy blue tie.

The first image was released in April 2016 to mark the Queen’s 90th birthday, with the picture then printed on commemorative stamps.

The youngest royal’s elevated position in the new portrait is reminiscent of the 2016 photo, when then-two-year-old George stood next to his great-grandmother on a blue and black step, holding the hand of his father, William.

Both the 2016 and 2020 images were taken by photographer Ranald Mackechnie.

The new snap comes just two weeks after the royals marked the festive season with another series of photos.

The Queen, Charles, William and George made Christmas puddings in Buckingham Palace last month, pictured in front of a Christmas tree adorned with regal corgi and crown decorations.

In footage that was played during the Queen’s Christmas message, George was seen repeatedly stabbing the thick pudding mixture with a wooden spoon, making his grandfather chuckle.
