The Princess of Wales proved last night that no other royal understands the art of state banquet dressing as she does.
Catherine, 43, was breathtaking in a sweeping pale blue Jenny Packham gown as she joined the Royal Family in welcoming the German president and his wife for their first state visit to the UK in nearly three decades.
Royal fans exclaimed with delight as they noticed the future Queen’s crowning jewel – Queen Victoria’s Oriental Circlet tiara – that is rarely seen.
It was fitting, however, that Catherine’s latest tiara was also her biggest one yet, as the towering diadem marked her state banquet evolution over the last decade.
Last night, Catherine didn’t just arrive in another dazzling gown; the royal brought with her the quiet reassurance of woman comfortable in her role as the ‘unrivalled architect of modern couture diplomacy’.
‘Kate Middleton’s state-banquet evolution has been playing out for years, but last night’s appearance proved beyond doubt that she is now the unrivalled architect of modern couture diplomacy,’ celebrity stylist Clare Chambers told the Daily Mail.
The princess has not always dressed this way. When she first married into the royal family, her evening gowns were sweeter, softer, and a touch more romantic as they echoed her early years in The Firm after marrying Prince William.
And last night, Catherine certainly looked worlds away from the ‘anxious’ princess who attended her first state banquet, when the late Queen hosted the then-Chinese President Xi Jinping at Buckingham Palace, in October 2015.
For the occasion, the then-Duchess of Cambridge picked a custom-made Jenny Packham dress – with cap sleeves – in the colour of China’s flag. She accessorised with the delicate pearl and diamond Lotus Flower tiara.
It was appropriate and flattering as the sweeping red gown, believed to be worth around £2,600, featured a slim-fitting waist with a belt and tailored top.
The next time Catherine attended a state banquet was in 2017 when Spain’s King Felipe and Queen Letizia travelled to the UK. The occasion also marked the first time Prince Harry, then 32, participated in a State Visit.
The Duchess, 35 at the time, donned the Cambridge Lover’s Knot tiara – which she also wore for Wednesday night’s reception – that was beloved by Princess Diana, as she picked a dusky Marchesa pink lace dress for the evening’s look.
She drew further attention to her décolletage with an eye-catching diamond and ruby drop Boucheron necklace, which once belonged to the Queen Mother.
The jewels fell just inches above the lowest point of the V-neck. The gown was beautiful, frothy and unabashedly Hollywood, the sort of dress worn by a young royal still finding her footing in a centuries-old institution.
The gown was a surprisingly revealing choice for the duchess and a departure from the conservative cuts she usually favoured – but as her responsibilities grew, the necklines began to rise.
‘The raised neckline symbolised a woman stepping firmly into queenship, embracing the gravitas of her role with both sartorial discipline and quiet certainty,’ Ms Chambers explained.
‘It also underscored the careful balancing act she now performs, glamorous enough to command attention, modest enough to honour tradition, impeccable enough to represent the monarchy at its most formal.’
While Catherine has always been considered a style icon, one of her earliest state banquet gowns for US President Donald Trump’s first official visit in 2019 did not play to her strengths, according to experts.
Wearing white in the form of a ruffled Sarah Burton for Alexander McQueen gown, the frothy fabric gave Kate a Disney princess feel rather than the polished princess she is now.
Perhaps taking a style tip from the US First Lady Melania Trump by accessorising with a pair of opera gloves could have added structure and elegance with less skin on show.
Over the past five banquets and, since she became the Princess of Wales in 2022, there has been a deliberate refinement of her state banquet style in line with her deepening understanding of what these nights signify.
Catherine put her best fashion foot forward in a gem-embellished white gown from her favoured Jenny Packham as she joined Prince William, King Charles III and Queen Camilla for the reception in honour of South Africa’s President Cyril Ramaphosa.
Following the late Queen Elizabeth’s death in September 2022, it saw the Prince and Princess of Wales play their most prominent role at such an engagement – which are undertaken at the request of the Government.
With its high neckline and full-length sleeves, the dress suggested Catherine had stepped confidently into her role while carrying herself with the grace expected from members of the Royal Family.
Ms Chambers suggested that the mother-of-three understands the visual language of royal eveningwear and the monarchy’s long history of formal dressing.
‘What makes Catherine’s state-banquet style so consistently successful is her ability to balance tradition with a modern sensibility, moving with the times whilst respecting the history of the royal family and this event.’
Over the years, Catherine appears to have found her most flattering silhouette: fitted through the waist, with a gently flared skirt and crisp lines that frame her royal orders, allowing her tiara and jewellery to shine.
She also appears to favour cape sleeves as Catherine made a glittering return to form at what is being described as her state banquet best last night.
‘Cape sleeves are Kate’s superpower,’ one fan wrote on X/Twitter within minutes of her arrival.
Another shared, ‘At this point, she’s single-handedly bringing back the cape. No one wears it better.’
These sleeves, once a bold experiment, have become the cornerstone of her banquet identity.
According to Ms Chambers, they give her the kind of regal presence that feels both timeless and entirely modern, a fresh take on the demure long-sleeved gowns worn by queens of the past.
Explaining why Catherine wears the style again and again, she added: ‘It plays to her strongest features.
‘She has great arms that complement her figure and she knows they need to be covered for a state banquet.
‘A long-fitted sleeve could easily drown or age her, and a voluminous sleeve would swallow her frame, so this is the perfect combination.’
Of course, this return to her signature style comes after a brief diversion in 2023 when the mother-of-three experimented with dramatic opera gloves in another custom Jenny Packham creation.
The gown, donned by Catherine at the state banquet for Korean President Yoon Suk Yeol and his wife Kim Keon Hee, featured floaty short sleeves adorned with gold beads and her arms stayed covered with white opera gloves.
She also debuted the Strathmore Rose Tiara, a piece which dates back to 1923.
However, style experts felt the look was a touch too theatrical for a state banquet.
Thankfully, by the following banquet, she had abandoned the gloves and reverted to the billowing caped sleeves that have since become her sartorial calling card.
Last night’s gown followed that template precisely, with this formula for the future Queen becoming something of an unspoken ritual.
Each iconic gown feels like a continuation of the last, not a repetition but a refinement.
The consistency is serene, almost ceremonial.
