“A Mulberry coat from their 2015 pre-fall AW collection, first worn by Kate in the same year, made another appearance last month.
“This sends a positive message and shows that she is unafraid to recycle classics.”
Not only is the Duchess championing sustainability with her own outfits, she seems to have done this with her children as well.
Even for important official portraits, the royal children will sometimes repeat outfits they have worn before.
Prince George wore a pair of dark blue shorts with a white shirt in portraits taken after Charlotte’s birth in 2015 and again in 2016.
This is a style the young Prince has been seen in many times and is reminiscent of other royals before him, including Prince William’s look at a child.
Kate may choose this style to give a subtle nod to royals before her.
Princess Charlotte has also opted for recycled looks on more than one occasion.
In November and December 2015, the Princess wore a pink floral dress and matching cardigan.
Kate Stacey added: “Kate is fond of championing British brands and she chooses well.
“The items she wears sell out within minutes – labelled the Kate-effect’.”
Although Prince Louis is seen less often, it is likely Kate is happy to recycle looks with him as well.
How did Kate Middleton become a royal?
Kate Middleton, or Catherine, Duchess of Cambridge, was born on 9 January 1982 at the Royal Berkshire Hospital, Reading, England.
She was born to Michael and Carole Middleton, a former flight dispatcher and air hostess. The couple founded a party supplies company, Party Pieces, in 1987 – now estimated to be worth £30 million.
Kate has a younger sister Pippa Matthews, 34, and a younger brother James Middleton, 31.
Kate and her family moved to Amman, Jordan, in 1984, where the future Duchess was educated at an English-speaking nursery school.
After moving back to Berkshire the family sent Kate to private school, St Andrews School. She went on to briefly study at Downe House before moving onto Marlborough College where she boarded.
For university the young Kate attended the University of St Andrews in Fife, Scotland. Here she was awarded an undergraduate MA (2:1 Hons) in history of art.
Relationship with Prince William
Kate met Prince William when they were both studying at St Andrews, and both living in St Salvator’s Hall. Famously, William reportedly took a fancy to Kate after she wore a see-through dress during a fashion show.
In 2003 the couple began dating and lived together during their second year of university.
The couple split in April 2007, however, in October they were back together.
Prince William proposed to Kate Middleton with his late mother Princess Diana’s engagement ring in October 2010. The couple were holidaying in Kenya at the time.
On 29 April 2011 they married at Westminster Abbey with a whopping 26 million watching the event live.
Kate wore an Alexander McQueen dress worth a reported £250,000 on the big day.
Kate assumed the title “Her Royal Highness The Duchess of Cambridge” and also become the Duchess of Cambridge on the day.
