This is why Meghan Markle can't wear a certain type of shoe around The Queen

At some point or the other, we've all fantasised about becoming a princess, and as such, the royal wedding between Meghan Markle and Prince Harry was the ultimate form of voyeurism. From gawking at Meghan's stunning but understated gown - Givenchy by way of Clare Waight Keller - to keeping tabs on her meaningful accoutrements - the late Princess Diana's aquamarine cocktail ring being her "something blue" - the majority of us couldn't help but pay close attention to it all.

But now that the nuptials are over, and Prince Harry and Meghan Markle's honeymoon is drawing to a close, it's evident that the real work is beginning for the Duchess of Sussex. For starters, she will purportedly be undergoing six months of "Duchess training" with the Queen's assistant private secretary, and not to mention, there's a slew of things that the erstwhile Suits actress will have to get used to not doing... such as wearing a certain style of shoe.

While being a member of the royal family means that you have the world's best fashion designers at your disposal, there are some fashion rules that Meghan Markle and her sister-in-law Kate Middleton have to follow.

Certainly, The Duchess of Cambridge is well known for wearing trendy footwear, and has stepped out in a number of styles including court heels, sporty trainers and strappy sandals.

However, there is one type of shoe that both Middleton and Markle will never wear around the Queen. Yes, while Middleton has been spotted wearing navy and camel coloured wedges at public outings, strangely she's never worn them while the Queen is around.

According to Vanity Fair, the 91-year-old monarch does not like the look of wedges. "The Queen isn't a fan of wedged shoes," a source told the publication. "She really doesn't like them and it's well known among the women in the family."

Markle has to follow the same royal fashion rules, and consequently, she will also have to avoid wedges when attending outings with the Queen.

But this is not the only thing that the 36-year-old will have to give up. While it's well known that Markle has a keen political sense, it's unlikely that she will participate in future UK elections, even though she has been granted British citizenship following her marriage to Prince Harry.

The official parliament website states: "Although not prohibited by law, it is considered unconstitutional for the Monarch to vote in an election." Although this primarily applies to Queen Elizabeth II, a spokesperson from Buckingham Palace told Newsweek in June of 2017 that extended members of the royal family opt not to vote "by convention".

Well, there you have it. Being a princess isn't all that it's cracked up to be - I mean, I don't know about you, but I would hate to give up wedges, even for a stud like Prince Harry...
