However, it seems they're not the only royals who have the Midas touch when it comes to pulling together an outfit. Alongside other princesses from around the globe, there's one sovereign in particular who's been serving up some standout ensembles of late: Queen Letizia of Spain.
The wife of King Felipe VI of Spain, Queen Letizia is fast becoming known for her flawless attire. Sure, she might have the world's greatest designers queuing outside the castle to dress her, but just like Kate Middleton and Meghan Markle, she often opts for more affordable brands, too.
Her innate knack for the high/low mix ensures she always looks the polished part whilst still tapping into major trends. From the regal uniform of frock coats and matching accessories to daring minidresses and bold displays of colour, she's a force to be reckoned with on the royal fashion circuit. Continue on below and you'll see why Queen Letizia's style is worthy of all the hype.

Queen Letizia knows the most elegant way to wear an off-the-shoulder dress is to keep the hemline below the knee. Chic, chic, chic.

The dress, we like. Those Perspex-strap courts, we love.
We can just see Kate Middleton channelling this denim look at next year's polo. The knee-length hemline is ideal for running after the royal tots.

Queen Letizia loves a jumpsuit, and this has to be one of her best. The one-shoulder detailing and draped train give it royal grandeur, whilst the navy hue and minimal use of accessories ensure it doesn't look over-the-top.
A Queen in a minidress? Letizia makes her own rules at the Francisco Cerecedo Journalism Award ceremony in Madrid. If Kate Middleton or Meghan Markle attempted to step out in this, the queen would likely tell them to go back upstairs and change.
She's already bought into autumn's favourite print.
That's right—Queen Letizia wore your newfound favourite skirt before this season's penchant for leopard print was even a thing.
She makes a case for classic hues.
Having to look polished 24/7 is hard graft, but Queen Letizia knows she can never go wrong with a neutral ensemble.
