Where Did Kate Go To School?
During the period May 1984 to September 1986, the Middleton family lived in Amnam, Jordan as Kate’s father Michael worked for British Airways. Therefore, Kate attended an English speaking nursery.

When the family returned to Berkshire in 1986, four-year-old Kate attended St Andrew’s School. She then went on to enrol at Malborough College, a boarding school in Wiltshire. The duchess then studied History of Art at St Andrew’s University until 2005.
Kate is renowned for her sartorial taste therefore it’s hardly surprising to learn that she once worked within the fashion industry. In November 2006, the duchess joined Jigsaw as an Accessories Buyer, where she worked part time for a year. She also worked until 2011 at her parent’s business, Party Pieces.

Sister Pippa also worked at the company following her graduation from the University of Edinburgh with a degree in English Literature. Kate was responsible for catalogue design, marketing and photography.

Kate first met William back in 2001 when the couple were both studying at the University of St Andrews. The pair started dating a year later, though it was never publically confirmed.
It was reported in April 2007 that Kate and William had separated during a holiday in Zermatt, Switzerland.

Kate's Wedding Dress
As the royal wedding loomed, media attention speculating which designer Kate would choose on the big day grew. It wasn't until Kate stepped out of the wedding car that it was revealed that Sarah Burton, creative director at Alexander McQueen, had designed the gown.

The dress undoubtedly received global acclaim, leading it to be exhibited at Buckingham Palace during the summer of 2011. The wedding dress was said to have referenced Princess Diana's own gown. Designer Vera Wang said: "Diana's dress had a sense of innocence, whimsy, almost storybook romance. In contrast Catherine's gown was about way more than simply the dress. Sarah Burton channelled a new take on classicism for a modern-day bride who will one day be Queen."
While the gown also gained the approval of fellow designer Karl Lagerfeld as he told France 2 Television: "The dress is classic and goes very well in the Westminster decor. "It almost reminds me of [Queen] Elizabeth's wedding, the royal weddings in the 1950's. The proportion of the train is good. The lace is very pretty. I like the veil a lot."

According to the Daily Mail, the duchess was also rumoured to have done her own make-up for the big day after taking private lessons from London-based make-up artist Arabella Preston.
Kate Middleton And Prince William's Children
Kensington Palace announced that Kate Middleton was expecting her first child back on December 3 2012. The news was declared before the duchess reached the 12-week mark as she was rushed to hospital after suffering from hyperemesis gravidarum.

She gave birth to a son on 22 July 2013 at 4.24 pm. The same easel that announced Prince William's birth back in 1982 was used to announce the arrival of their first child. The couple named their son, George Alexander Louis. Prince George is third in line to the throne.
On September 8 2014, Clarence House announced that the Duke and Duchess of Cambridge were expecting their second child. Again, the couple declared the news early due to Kate suffering from morning sickness for a second time.

The duchess gave birth to a daughter on 2 May 2015 at St Mary's hospital, where both Prince William and his son George were also born. The couple named their newborn daughter Charlotte Elizabeth Diana, in tribute to her late grandmother Princess Diana and her great-grandmother, Queen Elizabeth II.
And Princess Charlotte's birth undoubtedly marked a monumentous change in royal history. Soon after the Prince William and Kate Middleton wed, the 'Succession to the Crown Act' was altered, meaning that princes no longer take precedence over their sisters. Therefore, Princess Charlotte has overtaken her uncle Prince Harry in the line to the throne, as she is now fourth behind her elder brother, Prince George.
On 11 June, Princess Charlotte made her first public appearance on the balcony of Buckingham Palace following Trooping the Colour.
Pippa Middleton's Wedding
Kate Middleton attended sister Pippa's wedding on 22nd May, 2017. Kate was not a bridesmaid however, as she didn't wish to distract the attention from her younger sister on her big day. This is also the reason behind Prince Harry's girlfriend Meghan Markle's absence.

But Kate made sure to gave sister Pippa a memorable wedding gift. The Duchess of Cambridge sketched a drawing of St Marks' Church in Englefield, which was printed on the front of the guests' order of service booklets.
Kate Middleton's Style
There's no denying the sartorial influence that the Duchess of Cambridge possesses. Dubbed the 'Kate Effect', her royal wardrobe has inspired cult items to sell out within minutes, whether they are from LK Bennett, Zara or Mulberry. Her influence on fashion even led one brand in particular into financial trouble following an influx of pre-orders.

The Duchess of Cambridge is also renowned for repeating her greatest outfits, a sartorial trick Princess Diana once played. That is of course one reason for the remarkable resemblance between the late princess and Kate's wardrobes. The duchess often pays sartorial homage to the Princess of Wales, frequently donning one of Diana's most cherished brands, Catherine Walker.

Kate has even worn some of the late Princess of Wales' accessories including the iconic 'Cambridge Lover's Knot' tiara. The 19-tiered diamond crown was given to Princess Diana by the Queen as a wedding gift back in 1914. Kate has donned the glittery piece for many royal occasions. Most recently, the duchess wore the tiara to the annual Diplomatic Reception.
