Since her royal wedding back in May this year, Meghan Markle has adapted to royal life very well indeed. Despite the drama surrounding her family, Meghan has been handling her royal duties with grace and ease, with her new title of "Duchess of Sussex" befitting her extremely well too.

But the former Suits star hasn't quite let go of her past. Though she's busy learning all the ins and outs of royal tradition, as well as British culture, Meghan has stayed true to her glamorous past with her fashion choices.

Though her wardrobe is paid for by the royals and most likely pre-approved by some kind of PR/style team, Meghan is serving up look-after-look that is launching trends everywhere. Reports state that Meghan's outfits of the past year have inspired people to search for clothes of a similar style, meaning that clothes with boat necklines, trench dresses and strappy heels have been hotly-requested items.

But while the public might love her Duchess-worthy outfits, it seems that her grandmother-in-law, Queen Elizabeth II, might have another opinion. While she presumably digs Meghan's style like the rest of us, there is one particular sartorial pet peeve that the Queen apparently can't stand... and Meghan happened to be wearing it this week.

Like anyone's grandmother, you'd think the Queen doesn't like ripped jeans, see-through tops or sneakers that are too muddy. But you can bet that none of those things would be found in Meghan's closet nowadays.

No, it was something else entirely.

Prince Harry and Meghan went to the WellChild Awards on Tuesday, an event to honour sick children and their caregivers. It was a jovial affair, where the couple met with children and revealed their favourite Disney movies (Meghan loves the Little Mermaid and Harry's favourite is the Lion King).

But it was Meghan's outfit that sparked another conversation entirely. Meghan wore a black pantsuit, and while it might not look like much of a scandal to you or me (I think she looks bangin', personally!), it's reportedly not something that the Queen is fond of at all.

It's reported that the Queen doesn't like royal women being in suits, and would prefer if they only wore skirts and dresses.

A source told People: "Meghan has found certain rules in the royal household difficult to understand, like the fact that the Queen prefers women in dresses or skirts rather than trouser suits, and is often asking Harry why things have to be done in a certain way."

It's not the first time Meghan has worn a pantsuit either.

But who cares? She's her own woman and frankly, she's rocking it.

And to be fair, the Queen used to wear trousers all the time when she was younger. Even now she wears them from time to time.

Lizzie wore this decidedly more casual look back in August 2010 when she was stepping off a cruise ship in Scotland. So even if she "prefers" royal ladies to stay smart in skirts and dresses, the Queen also knows the virtues of trousers.

You do you, Lizzie, and let Meghan be too.

Since becoming a royal, Meghan Markle has gone about her business pretty well. While she was undoubtedly famous and successful in her own right before marrying into the family, her status has been elevated to another playing field and she has dealt with it all remarkably. However, for all the praise she has been receiving, Meghan has also attracted a fair amount of scorn from royal commenters.

From the outside looking in, Meghan Markle seems to have set out on a one-woman mission to revolutionise the royal family and bring them into the 21st century. Her wedding to Prince Harry was heralded as the most modern royal occasion in recent history, with there being plenty of aspects of the ceremony that went against what we're used to seeing from the often outdated and archaic family.

Whether it was the presence of a black American pastor, the music provided by a gospel choir or Meghan wearing a statement, feminist-inspired dress from Givenchy, there was a lot to marvel at on the big day.

But, for all the good she has done in the family, Meghan still receives a fair amount of criticism online, with the majority of comments focusing on what she wears to royal engagements.

Firstly, there was the ridiculous criticism she attracted for daring to show her shoulders off at a royal engagement, with commenters saying that it wasn't appropriate and she shouldn't be doing it. And then, even more ludicrously, Meghan received widespread criticism for "not sitting correctly" during a photo with the Queen and Prince Harry.

However, while Meghan may have received criticism from those outside of the family, it's believed that her in-laws are big fans of the former actress. Despite this, it's now being reported that Meghan has had a warning about the clothes she wears, with Harry taking particular issue with one item of clothing that she has previously worn.

The couple is preparing for an official visit to Australia and neighbouring islands this Autumn, with Kensington Palace tweeting: ''The Duke and Duchess of Sussex will undertake an official visit to Australia, Fiji, the Kingdom of Tonga, and New Zealand in the Autumn. The tour will fall on the occasion of @InvictusSydney 2018. (sic)''

Of course, for Meghan in particular, this means that she needs to begin thinking about what she is going to wear for the engagement. According to a source that spoke to the Daily Mail newspaper, ''Meghan is being told she needs to stop dressing like a Hollywood star and start dressing like a royal. Meghan wanted to wear a tuxedo-style suit but Harry said it wasn't traditional enough.''

Meghan has previously worn a suit out before, but it's believed that the Queen prefers to see women in dresses, skirts and suitable footwear.

While it may be the royal protocol for Meghan to wear a dress or skirt, what does it really matter? Personally, I'd prefer to see her step out in a Nike tracksuit and trainers - it would go some way to making the Royals a little more relatable.
