Be it elders or children, royal family members are subject to several grave protocols, ranging from how they travel and what is their dress code.

However, Kate Middleton and Prince William’s eldest son Prince George violated the royal rule by donning a robe to meet heads of state, Hello Magazine reported.

Before we delve into when and where Prince George breached the sartorial standard, let’s first understand what the royal dress code is all about.

In a video posted on YouTube’s The Royal Family Channel, Debrett’s etiquette expert Lucy Hume has outlined the three major royal dress codes necessary to maintain while meeting guests. The first dress code includes white tie, which is appropriate for state banquets or royal events.

This is similar to males wearing black tie and a white tuxedo with a wing collar, while women would traditionally sport a long, formal evening gown.

Black tie events require a “shorter dinner jacket for men and a black bowtie” as the next degree of formality.

However, women have more choices when it comes to opting a dress for themselves, as they can pick between a trouser suit and a cocktail dress. The last smart casual dress code allows the royals to wear comfy attire, such as a jumper and collared shirt.

The Princess of Wales revealed the diagnosis before pleading with the public and the world to finally allow her and her family privacy as she begins to treat the form of the disease that she’s battling with, and it sounds like it’s taking a huge toll on her. “Kate and William are going through hell behind palace walls,” a high-level royal courtier told the National Enquirer. The source added that the Royal couple are going to “great lengths” to hide the disease from their three children.

However, according to the insider, it’s also becoming more difficult to hide the news from Prince George, Princess Charlotte and Prince Louis are no older than 10 as the condition begins to devastate the Dutchess of Edinburgh. Middleton said she was beginning chemotherapy but that can have some brutal side effects such as nausea and vomiting, hair loss, fatigue and an increased risk of infection due to lowered white blood cell counts.

Mucositis can cause painful mouth sores, and gastrointestinal disturbances such as diarrhea or constipation are common. Neuropathy, which involves numbness, tingling, or pain in the hands and feet, can also occur. It’s not clear if Middleton has any, or all, of those symptoms but it is possible and it doesn’t paint a pretty picture for the future Queen of the United Kingdom and Commonwealth as she battles the condition
