SINCE tying the knot with Prince Harry in May, Meghan Markle has been learning the royal protocol expected of family members.
But while she has done a spectacular job on her royal tour, she did break one rule on the very last day.
Today, the pregnant duchess ditched her heels to go barefoot during a formal pōwhiri, which is a traditional Māori welcoming ceremony in New Zealand.
She was captured wearing deep red nail polish on her toes, which is frowned upon in the royal family.
According to OK! magazine, coloured nail varnish and fake nails are not part of the royal etiquette, and are typically considered to be “vulgar”, which is why Meghan typically opts for a subtle shade.
The Queen’s go-to polish, Essie Ballet Slippers, is the preferred royal polish, and thankfully only costs £7.99.
It's reported that the Queen has been wearing the Ballet Slippers polish 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.
The subtle shade works well with the Queen's many bright outfits and gloves and Kate Middleton has also become a firm fan.

Meghan’s barefoot ceremony today was part of her final day of appearances at the end of the royal tour.
Visiting Te Papaiouru Marae in Rotorua, the mum showed off her baby bump in a £2,159 navy Stella McCartney dress with three-quarter length sleeves.
Meghan was also given a Maori green-stone necklace made of jade, which was tied around her neck, and also wore Remembrance Day poppies.
The pair waved to fans as they stepped in to a car to conclude the mammoth tour.
They have been on a 16-day trip which has seen them travel to Australia, Fiji and Tonga, and they are now in New Zealand.
The pair has crammed in an incredible 76 engagements during their trip, and will return to Auckland this evening, before departing for London tomorrow.
In the past, Meghan has been mocked by cruel Twitter trolls over the shape of her feet, which have been described as "ugly, spidery, and bunion-ridden".
But British solestry expert Jane Sheehan, who has 20 years of experience analysing feet, said the royal’s feet indicate she is a born leader.
