The pretty brunette wore her hair up in a chic updo, giving centre stage to a stunning pair of royal blue stone earrings by Indian jeweller Amrapali. A delicate matching blue clutch completed the showstopping look for the Duchess's first night of their royal tour of India.
Speaking to Bollywood actress Madhuri Dixit, Kate admitted she was anxious about leaving Prince George and Princess Charlotte at home. "She said she loves being here and the people are very welcoming, but she was worried she may miss her children," Madhuri told reporters at the evening do.
For their last event of the day, Prince William and Kate were the picture of elegance as they attended a glittering Bollywood gala held in their honour in Mumbai.
The couple went on to visit the Banganga Water Tank in Mumbai where they were greeted by children dancing and playing lezim steel drums in honour of their arrival. The couple were presented with white, orange and pink garlands and a tika traditional welcome spot on their foreheads before placing floral tributes into the water as an offering.
William and Kate then embarked on a surprise open top bus tour of Mumbai,
joining the children from urban slums.
William and Kate visited The Social – a café and collaborative work space – where they met with some of the city's budding business talent and were given a chance to try out some of their new ideas. At one stand, the couple took turns to put on a blindfold and learnt how to type in Braille - very sweetly, they typed the word "George".
For their first engagement in Delhi the couple headed to India Gate – a 42m high sandstone structure that is considered the country's main war memorial – to lay a wreath of marigolds at the memorial to show their respects to the 70,000 Indian soldiers who lost their lives while fighting for the British Army during WWI.
Following their solemn engagement the Duke and Duchess travelled to Gandhi Smriti. Literally meaning 'Gandhi memory', the museum is located in Old Birla House, where Mahatma Gandhi, India's founding father, spent the last few years of his life. The couple were given a private tour of the museum and shown a giant bronze statue of Gandhi with two children.
William and Kate then retraced Gandhi's final footsteps from his humble bedroom to the spot in the garden where he was assassinated in 1948. Going barefoot, the Duke and Duchess also saw the prayer hall where Gandhi used to address his followers.
For the last engagement of day 2, William and Kate stepped out for a garden party in Delhi to celebrate the Queen's 90th birthday. Kate impressed fashion fans yet again with another Indian-inspired outfit, this time a stylish Alice Temperley crop top and skirt ensemble.
The black and white outfit, titled Delphia, featured opulent embroidery motifs of Indian Chintz and lattice. The top costs £1,995 while the skirt has a price tag of £1,995.
The couple then had the honour of cutting the Queen's birthday cake, but not before teasing each other about who would take the sword. William also gave a speech in which he praised his grandmother, and said that his children Prince George and Princess Charlotte are "lucky" to have such a "wonderful role model".
"I am incredibly lucky to have my grandmother in my life," he said. "As she turns 90, she is a remarkably energetic and dedicated guiding force for her family. "And I am so glad that my children are having the chance to get to know the Queen. George and Charlotte, too, will discover how lucky they are to have such a wonderful great-grandmother – a role model for the rest of their lives."
The Duke and Duchess of Cambridge kicked off day 3 of their royal tour by meeting a group of vulnerable young people in New Delhi. Prince William and Kate learned about the work carried out by charity Saalam Baalak, which provides care and protection to street and working children in Delhi and the surrounding areas
The Duchess turned heads with the elegant updo she chose for the occasion.
For their second engagement of the day, William and Kate met the Indian Prime Minister Narendra Modi.
The elegant royal chose a feminine but modern design in a beautiful jade green by one of her favourite designers, Alice Temperley, for the event. She completed her look with a pair of nude heels and her LK Bennett 'Natalie' straw clutch bag.
The royal couple arrived in Assam on Tuesday afternoon, where they were given a warm ceremonial welcome and greeted with bouquets of flowers.
Many fans had been wondering who had designed Kate's latest dress and the mystery was finally solved later in the day! The long-sleeved floral-printed maxi dress in question is from budget brand Glamorous and costs £50.
William and Kate had the chance to relax and settle down around a campfire, where they chatted and mingled with locals. They were treated to dance and musical performances – a colourful and very fun introduction to rural life. As their visit coincides with the Bohag Bihu harvest festival, which marks the beginning of Assamese New Year, the royals were also given an insight into how the locals celebrate.
The couple were particularly impressed by the dancing of a three-year-old boy and sought him out to meet him after the performance. "You were very energetic," William told the youngster, before adding: "He knows his dancing very well."
It was an early start for the royal couple on day four of their royal tour, as they headed off on safari at Karizanga National Park.
The park is a World Heritage Site and a wildlife conservation area of global importance, home to elephants, water buffalo, the endangered swamp deer, tigers, and two-thirds of the world population of Indian one-horned rhinoceroses.
The couple enjoyed an open-air Jeep ride around the National Park, where they caught sight of rhinos and baby elephants. The final 30 minutes of the trip offered some private time for William and Kate, as they were left to finish their journey without the media and just a few protection officers.
Then Kate - a keen and talented photographer - decided to take out her Canon DSLR camera to capture some of her own photos.
The Duchess admitted to missing Prince George and Princess Charlotte during the couple's visit to Panbari village, which sits on the border of Kaziranga National Park. While talking to the village elders, William and Kate joked that George was "too naughty" to join them on their royal tour, but promised to bring along their children on their next visit to India.
Kate once again championed the British high street for her visit to the village, wearing a Topshop midi dress and Accessorize earrings.
On their next engagement of the day, the couple visited the Centre for Wildlife Rehabilitation and Conservation, where they had the opportunity to feed baby elephants and rhinos. Vernon Menon, chief executive officer of the Wildlife Trust of India, said the couple were "thrilled" at the opportunity to get so close to the animals.
"They were absolutely thrilled and loved being with the animals," he said. "The Duchess loved the baby rhino particularly. The Duke said if he could he would have spent the whole day there."
