Did Meghan Markle break another Royal Protocol?

Seems like The Duchess of Sussex doesn't want to abide by rules of The Royals!

Meghan Markle, who made an unannounced appearance at the British Fashion Awards held at Royal Albert Hall in London on Monday, seems to have broken another royal protocol by wearing dark nail paint.

According to Vogue Australia, wearing a nail colour darker than Queen's favourite pink or a nude shade is an unofficial offense. Although the rule has never officially been confirmed as a strict order, but nonetheless, no other royal ladies have openly decided to ignore them in years.

Meghan, who looked ethereal in a one-shoulder black silk Givenchy gown, delved into a whole other spectrum of maroon nail colour, probably to match her dress. She complimented her look with a sleek bun and golden heels and bracelets.

Since the announcement of her engagement to Prince Harry, Meghan has generally followed this rule at various events.

But, this is not the first time Meghan ditched the rules. Back in July, she debuted a dusky pink sleeveless trench on a visit to the Nelson Mandela Centenary Exhibit at London's Southbank Centre with her husband.

Also, Meghan had a fashion faux pas on her six-day royal tour of Australia and South Pacific. She accidentally left the tag at the bottom of her self-portrait dress which read "Returns will only be accepted if this tag remains attached".

The royal couple, who got married at Windsor Castle's St. George's Chapel on May 19, is also expecting their first child in 2019.
