since 1989.
According to the brand's website, Queen Elizabeth's hairdresser wrote to the brand's owner, nail polish-mogul Essie Weingarten, asking for a bottle of the light pink polish as she didn't want to wear any other.
That said, Meghan did adhere to royal protocol when she wore a similar shade for baby Archie's first photocall .

Despite this, Meghan jetted to New York to celebrate with pals - including Serena Williams, Jessica Mulroney and Abigail Spencer - in February 2019.
What's more, the Queen's former aide branded the baby shower "over the top" and "very much an American thing".
The baby shower reportedly cost £330,000, with the mum-to-be given lavish gifts for Archie, including a £290 crib.
Pregnant Meghan was also said to have taken a £95,000 private jet to her star-studded bash, which took place at the prestigious The Mark Hotel.
Archie's birth Meghan Markle and Prince Harry introduced Archie to the world's press at a Windsor photocall Credit: PA:Press Association While Prince William and Kate Middleton introduced their three children to the world just hours after they were born, Meghan Markle and Prince Harry took a drastically different approach.
The Duchess of Cambridge followed in Princess Diana and Princess Anne 's footsteps when she gave birth at the Lindo Wing in London.
The Princess Royal had her first child Peter Phillips there in 1977, followed by daughter Zara in 1981.
Diana chose it for the births of William in 1982 and Harry in 1984 and Kate followed in 2013, 2015 and 2018 with George, Charlotte and Louis.

"The Duke and Duchess look forward to sharing the exciting news with everyone once they have had an opportunity to celebrate privately as a new family."
However, Archie's birth certificate confirmed that the royal tot had been born at the Portland Hospital at 5:26am on 6 May 2018.
In his new book Battle of Brothers, royal expert Robert Lacey wrote: "Harry and Meghan were resolute that their newborn baby's first sight of the world should not be the same insane and lethal camera-flashing that had attended — had actually brought about — the death of Diana."
Instead, the couple introduced Archie to the world two days after his birth at photocall in Windsor.
'Blinged up' engagement ring Meghan Markle appeared to have 'blinged up' her engagement ring in 2019 Credit: Alamy Live News When Prince Harry popped the question in 2017, he did so with a ring he'd designed himself.
The Duchess of Sussex's stunning sparkler even features two of the late Princess Diana 's diamonds - but at the Trooping the Colour less than two years later, it's had undergone a dramatic transformation.
The envy-inducing ring originally had a thick gold band which beautifully offset the row of three diamonds.
However, the Duchess reset her ring with a much thinner, diamond-studded micro-pave gold band.

"I find it a bit odd Meghan would want to alter a ring that her husband had especially designed for her," she said.
"A royal engagement ring is a piece of history not a bit of jewellery to be updated when it looks old fashioned."
Archie's private christening and anonymous godparents Meghan and Harry have never revealed the identities of Archie's godparents After keeping the details of his birth private, it's hardly surprising Meghan and Harry took an unconventional approach with Archie's christening too .
Determined to make their son a "private citizen", the couple planned a media-free baptism in Windsor with just 25 guests.
And unlike Kate and William, the couple have never revealed the identities of Archie's godparents .
Despite breaking protocol with the private ceremony, Meghan did conform to tradition by dressing Archie in a gown that is a replica of the one Queen Victoria commissioned in 1841 .

In the documentary Harry & Meghan: An African Journey , the Duchess opened up about the struggles she's encountered since becoming a Royal and admitted she wants to "thrive" in her royal role instead of merely "surviving".
Meghan admitted: "I've said for a long time to H - that's what I call him - it is not enough to just survive something, right? That's not the point of life. You've got to thrive.
"You've got to feel happy and I think I really tried to adopt this British sensibility of a stiff upper lip. I tried, I really tried."
First royal voter Meghan and Harry have been urging the public to vote in the upcoming US election Credit: AP:Associated Press Now that she's stepped down as a senior member of the Royal Family , Meghan Markle is free to vote in the upcoming US election .
Although members of the Royal Family are technically able to vote, they are expected to be above politics and as such voluntarily refrain from casting votes.
In September, Meghan called presidential election “the most important of our life” filmed in the garden of their £11m Montecito home.
"Every four years we are told the same thing, that this is the most important election of our lifetime," the Duchess said. "But this one is. When we vote, our values are put into action and our voices are heard. Your voice is a reminder that you matter, because you do and you deserve to be heard."
Meanwhile, Harry urged voters to “reject hate speech, misinformation and online negativity” which social media users saw as an attack on Donald Trump .
The Sussexes pledged to “uphold the values of Her Majesty ” in their Megxit deal - which includes remaining politically neutral.
A royal aide told The Sunday Times: "The family are all wringing their hands, thinking, ‘Where is this going?’ The feeling is it’s a violation.”
