Since Meghan announced her engagement to Prince Harry in November 2017, she’s quickly had to learn some rather particular rules when it comes to royal etiquette.
From learning how and when to curtsy and refraining from eating one of her favourite foods in front of the Queen, to adopting an entirely new style, the Duchess of Sussex is continuing to adjust to her new royal life with grace and poise.
However, becoming a new royal has also meant the former actress had to give up some of her favourite pastimes including her now defunct lifestyle blog, The Tig, and social media accounts.
Meanwhile, her new relatives - Princess Eugenie and Princess Beatrice - appear to follow a different set of royal regulations.
With Beatrice’s wedding scheduled for October 2018 at St George’s Chapel - the exact same location of Meghan Markle’s recent nuptials - we take a look at the different rules in place for the two royals.
1. Beatrice can wear dark nail polish
Following in the footsteps of the Queen and the Duchess of Cambridge, who reportedly wear Essie Ballet Slippers nail polish, Meghan now also sports natural nude and pink shades despite having worn darker hues in previous years.
However, Eugenie has been able to sport a variety of coloured nail polishes over the years at public events, despite her royal title.
This might have something to do with the fact there is less spotlight on the princess with her now being ninth-in-line to the throne, while her cousin and Meghan’s husband Prince Harry is fifth. As a result, it's presumed she's allowed to play around with her style and beauty far more than Kate and Meghan who present more traditional and neutral looks.
2. Beatrice is allowed to have a job outside of the Royal Family
In the lead up to Meghan’s wedding to Prince Harry, the former actress hung up her actress title for good and announced she was leaving her beloved television show Suits. In turn, the Californian replaced one stage for another in her new role as a working royal, attending public events to give speeches and awards and meet the public across the world.
Meanwhile, despite her royal title, Princess Eugenie, nor her older sister, 29-year-old Princess Beatrice, are responsible for carrying out public duties. In fact, Eugenie actually works as an associate director for the Hauser & Wirth art gallery in London.
In 2013, the now 28-year-old moved to New York to work for the online auction firm Paddle8 as a benefit auctions manager after graduating from her Art History, English Literature and Politics degree at Newcastle University.
Following her marriage to fiancé Jack Brooksbank in October, it is widely believed Eugenie will continue being able to work in her current position and will be under no obligation to attend royal celebrations, unlike Meghan and Kate.
"Eugenie and her sister Princess Beatrice aren’t working royals, and that’s unlikely to change," James Brookes, Director of Broadcasting and Communications at Royal Central told Express.co.uk.
As a result, the bride-to-be is also not expected to take a carriage ride through Windsor, as Harry and Meghan did, as she has no official duty to the public.
3. Beatrice is allowed to have Instagram
Following the closure of Meghan Markle’s lifestyle blog The Tig in April 2017 as her relationship with the prince intensified, the now duchess bid farewell to her Facebook, Instagram, and Twitter accounts in January 2018.
At the time, Kensington Palace confirmed the star had shut down her social media accounts explaining that Meghan was "grateful to everyone who has followed her social media accounts over the years" but has closed them "as she has not used these accounts for some time".
Meanwhile, Princess Eugenie has an official Instagram account boasting 258,000 followers which she revealed on International Women's Day in March 2018.
The princess posts regular updates on the social media platform about her personal and professional life, throwback images to when she was a child, book recommendations, and her struggles with Scoliosis.
4. Beatrice can wear shorter dresses
Last month, Meghan suffered the wrath of royal fans who criticised her decision to wear an off-the-shoulder Carolina Herrera pink dress to the Trooping the Colour, suggesting she broke royal protocol with the ‘revealing’ dress.
It is widely believed women in the Royal Family must wear dresses and coats with knee-length hemlines (generally no more than three or four inches above the knee) and skin-coloured tights. This might explain then why we’ve seen Kate and Meghan wearing so many knee-skimming dresses and nude hosiery since entering the Monarchy.
That said, Princess Eugenie is often seen in shorter ensembles sans tights and was one of very few guests at Prince Harry and Meghan Markle’s royal wedding to sport a short hemline - in her case, a blue bespoke Gainsbourg dress.
In fact, Beatrice and Eugenie are rarely seen wearing tights, suggesting royal fashion rules are far more lax for the pair in comparison to Meghan and Kate.
5. Beatrice didn’t have to ask official permission from the Queen to marry
Earlier this year, Kensington Palace announced Queen Elizabeth had granted her official blessing for Prince Harry and Meghan to marry.
Why? Because prior to 2013, the 1772 Royal Marriages Act dictated that all marriages to members of the British royal family had to be approved by the monarch and furthermore, if a descendent of the king or queen married without consent, that marriage would be considered null and void.
But in 2013, that centuries-old law was replaced by the Succession to the Crown Act, which states that only the first six in line to the throne need the monarch’s consent.
As a result, Prince Harry was required to seek his grandmother’s approval to marry whereas Eugenie didn’t need to.
