During this two-day, whistle-stop Copenhagen visit, the Duchess of Cambridge seemed delighted to be in company of Denmark’s royal family and Crown Princess Mary.

This morning saw Kate Middleton officially welcomed to Denmark by Queen Margrethe II and Australian-born Crown Princess Mary at Christian IX’s Palace, and from the official photos taken, it’s clear that the English royal is very much at ease with her Danish counterparts. 

Indeed, the Duchess, 40, and Crown Princess Mary, 50, both wearing their long brunette locks flowing and opting for smart coat dresses – Kate wearing a £3,000 Catherine Walker coat dress while Mary chose a chic white number worn on previous outings – might have been mistaken for sisters. 

Both were not born into royalty and formed their first friendship in 2011. They looked comfortable together as they strolled outside Denmark’s royal palace.

At ease: The pair, neither of whom were born into royal life, looked entirely comfortable in each other's company as they strolled in the sunshine outside the official royal palace in the Danish capital

Both women have excelled in the roles they've been given since marrying into their respective royal families. Their fashion sense has often aligned too as they've been spotted frequently in similar stylish outfits. While Kate Middleton donned a £3,000 Catherine Walker coat dress, her Danish counterpart opted for a chic white coat with frayed hem that she's worn for a previous engagement

Since their marriages into royal families, both women have done well in all the different roles that they were given. They have often been seen in the same stylish clothes, which is a sign of their fashion sensibilities. While Kate Middleton donned a £3,000 Catherine Walker coat dress, her Danish counterpart opted for a chic white coat with frayed hem that she’s worn for a previous engagement

Like Kate, the Danish royal, 50, wasn't born into royal life. Crown Princess Mary was raised as Mary Elizabeth Donaldson and came from a very different place to her husband, Crown Prince Frederik

Kate was born in the royal family, but the Danish princess, now 50, didn’t get to be a royal. Mary Elizabeth Donaldson was Crown Princess Mary and her father, Crown Prince Frederik, were raised in different circumstances.

The visit is in part due to pay tribute to the historic ties Britain shares with Denmark and celebrate the countries' joint jubilees - the Queen's Platinum Jubilee and the Golden Jubilee of Queen Margrethe II of Denmark, both of which fall in 2022

In part, this visit will pay tribute to Britain’s historical ties with Denmark.

Given their similar lives, it is not surprising that there was such warmth among the royal contemporaries. 

After both marrying into royal families, Kate to Prince William in 2011, and Mary to Crown Prince Frederik in 2004, the commoners-turned-royals have thrown themselves wholeheartedly into public life, garnering legions of adoring fans in their respective nations.

Doting parents, while the Duchess of Cambridge is mother to Prince George, eight, Princess Charlotte, six, and Prince Louis, three, Crown Princess Mary has four children: Prince Christian, born in October 2005, Princess Isabella, born in April 2007, and twins Prince Vincent and Princess Josephine, born in January 2011.

However, Kate Middleton came from a wealthy background, and Kate Middleton is a product of that privilege. In 2001, the British Royals were in love with each other as they lived in the same room at St Andrews University.

Hers was an entirely different world, born to a Scottish math professor and his wife, on Tasmania, Australia. It is thousands of miles away from Copenhagen’s magnificent Frederik VIII Palace of Amalienborg, which she now calls home.

Synergy: The two women, born ten years apart, have a similar approach to fashion, and have often been spotted wearing almost identical outfits (Kate pictured in London in 2019)

Prince Frederik (now 53), was the man she met in Sydney’s Slip Inn pub. At the time, she was 28 years old and was working as a sales manager for a luxury real estate agency. He was also visiting Australia in 2000.

He is well-known for dating Scandi models as well as a pop superstar. It was, apparently, love at first sight. The couple married in 2004, and Mary was placed under Frederik’s tutelage by Queen Margrethe II (a Cambridge graduate and Sorbonne scholar). 

Mary, like Kate, quickly got down to work, became fluent in Danish, and is still highly respected by Denmark’s residents.

There are many parallels between Kate & Mary. The style similarities between Kate and Mary are evident when they look at their royal outfits, both formal and casual. They both look great in relaxed attire for casual outings or formal wear for special occasions.  

Each has managed to adapt with ease to the scrutiny that comes along with royal life. The confident Kate showed that, even without Prince William at her side, she could handle any royal engagement. 

She wore casual clothing to visit the Stenurten Forest Kindergarten, where she was photographed chopping wood with a group. The mother-of-three appeared relaxed in a grey jumper, which she paired with her £209 green Seeland wax jacket and a simple pair of black jeans. She finished off her look with her £170 boots from celeb-loved brand Blundstone.

He was seen racing with children around the woods with his hand and taking part in a variety of activities, such as splitting wood with a saw or running through the trails with other forest kindergarten kids.

Later today, the Duchess will continue her support of Crown Princess Mary by joining her to visit a project supported by the Page 2 of 2 Mary Foundation, founded in 2007 by the Danish royal, to protect vulnerable women and children from domestic violence.  

Also, she will be learning about Denmark’s approach to infant mental wellness and physical health.
