Kate reverts to favourite designer for red letter day: Duchess wears bespoke Jenny Packham gown for her first state banquet

The Duchess of Cambridge is nothing if not loyal to her favourite designers but when it came to choosing a stunning, appropriate and memorable gown for her first state banquet at Buckingham Palace, only one designer would do - Jenny Packham.

The floor-sweeping dress, made in a stunning red in honour of the Queen's guests Chinese president Xi Jinping and his glamorous wife Peng Liyuan - combined a fitted round bodice with a round neck and cap sleeves with a long romantic skirt and was also simple enough to offset the stunning diamonds given and lent by the Queen.

Kate, 33, wore Jenny Packham when she left hospital with both Prince Charlotte and George and turned to the designer for key pieces in her royal tour wardrobe in Australia and New Zealand, in a relationship the British dressmaker has described as 'collaborative'.

Whilst the biggest sartorial choice of our day might be what to put on in the morning, the Duchess of Cambridge faced a much more serious style decision today- what to wear for her first state dinner held at Buckingham Palace!

The event, held in honor of the Chinese president’s visit to the UK, also marked only the third time Kate has worn a tiara for an official engagement, causing much speculation about which of the royal jewels she would choose- decisions decisions!

Taking this diamond dilemma in her stride, Kate opted for the Papyrus tiara which set off her scarlet hued embellished gown perfectly.

Ever the sartorial diplomat, the Duchess of Cambridge flew the flag for the British fashion industry wearing a bespoke gown by Jenny Packham in red, which just so happens to be China’s national color- genius!

One of the Duchess of Cambridge’s go-to designers for official occasions, Kate also wore a dress by Jenny Packham earlier this year when she was pictured leaving hospital following the birth of Princess Charlotte.

Jenny Packham confirmed to FEMAIL that they designed the bespoke dress for the occasion. Similar looks retail on their website for £2,600.

The dress features many of the details Kate likes, including a slim-fitting waist with a belt and tailored top. The vibrant shade, which is also one of her favourite, referenced the national colour of China.

It also set off Kate's jewellery from the Lotus Flower Tiara perched in her elegant up-do, to the diamond bracelets on both wrists.

Jenny Packham has earned her place as the Duchess's designer of choice and the businesswoman has provided a glimpse into what it means to be the brains behind the woman with one of the world's most closely-watched wardrobes.

Packham's policy is not to discuss clients but she admits it can be difficult not to. Asked by WWD if she works directly with the duchess, Packham said, 'Absolutely. It’s always quite a collaboration.'

She also noted that the Duchess has a great sense of style and a British one.

Four-and-a-half years after she became an HRH, Kate made her first appearance at what is considered a staple royal duty - dining in the opulent palace ballroom with 170 guests in honour of a visiting president.

It was also the Duke of Cambridge's first state banquet in the UK.

Kate joined the Royal Procession into the Ballroom, following behind William who walked with Caroline Welby - the wife of the Archbishop of Canterbury.

Kate walked alongside Wang Huning, one of the Communist Party of China's top leaders.

She was seated in the most prominent position for a female member of the royal family after the Queen - on the President's right while the monarch, as is custom, sat on Mr Xi's left.

As the wife of the second in line to throne, Kate takes William's status when she accompanies him, so outranks blood princesses such as the Princess Royal, who was also present.

On Kate's right sat Mr Huning.

The Duchess appeared to join the First Lady in adopting a more informal appearance and eschewing traditional evening gloves.

Kate was expected to wear the Order of Elizabeth, which the Queen was believed to have awarded her, but there was no sign of the miniature portrait attached to a yellow ribbon.

Although only the third time she's worn a tiara, this is the second time the mother-of-two has showcased this stunning headpiece, indicating that like the Queen's late sister, this will become her tiara of choice for official dinners.

The Duchess wore a pair of chandelier diamond earrings loaned from Her Majesty as well as two eye-popping bracelets.

One art deco-style bracelet was fashioned into a bracelet from Queen Mary's choker while another dazzling bangle was one of Prince Philip's wedding gifts to the Queen, designed by Bond Street jeweller Philip Antrobus brilliants from a tiara belonging to Princess Andrew of Greece, the Duke of Edinburgh's mother, placed in a platinum setting.

Meanwhile, Ms Peng delivered on her reputation for glamour and style, thanks to her close relationship with Chinese designer Ma Ke, in a shantung silk midnight blue dress with a high neck and white belt.

Her Majesty opted for her signature state banquet look, going for a white gown, white evening gloves, her Order of the Garter sash and - in an unusual choice - the Modern Sapphire Tiara with matching necklace.

Prince William was resplendent in white tie by Kate's side as they arrived for the glittering sit-down dinner, which was hosted by the Queen in the palace's grand ballroom. 

It was held in honour of Chinese president Xi Jinping and welcomed 170 guests including Prime Minister David Cameron and Labour leader Jeremy Corbyn.

According to protocol, female members of the royal family must dress in evening gowns for state banquets and wear tiaras - often loaned to them by the Queen.

They must also wear the Elizabeth II Family Order - a jewel encased image of the Queen on a chartreuse yellow ribbon which royal women wear pinned to their left shoulder. The Duchess of Cornwall, the Princess Royal and the Countess of Wessex have all been given the personal order. 

Meanwhile it is also the Duke of Cambridge's first Palace banquet - despite William turning 33 this year. The Duke's father Charles was 20 at his first state banquet in the London residence, but William has been wary of signing up too early to the more restrictive life of a full-time royal.

The Cambridges' decision to attend demonstrates the diplomatic importance of the Chinese state visit. 

They did attend a state dinner in Singapore during their Jubilee tour in 2012, but it was a tiara-free affair.

Kate's widely anticipated inaugural banquet in the UK comes six months after the birth of her second child Princess Charlotte.

Guests including the Prime Minister David Cameron, Labour leader Jeremy Corbyn and other politicians and dignitaries dined around a grand horseshoe shaped table, extravagantly decorated with large floral displays and priceless dinner sets, beneath the palace ballroom's six impressive chandeliers.

The dress code, which was outlined on the invitations, states 'Evening Dress (White Tie), Decorations, Full Ceremonial Evening Dress for Serving Officers, or National Dress'.

It is intended as guidance, so guests are aware of what others will be wearing, and on occasion, some have worn black-tie instead.

Guests are traditionally received before the banquet by the Queen and the Duke of Edinburgh, shaking their hands and exchanging a few words of greeting.

Following the visiting leader's speech, the National Anthem is played by the orchestra and guests stand, but do not sing.
