Like us mere mortals, the royals are prone to the odd wardrobe malfunction. Prince Harry joked about this mishap on his wedding day, Queen Elizabeth's tiara broke hours before her vows, while Princess Diana's dress was famously creased on her big day.

So it's no surprise they've become quite nifty when it comes to their outfits. Kate Middleton has a great bra hack for sheer dresses, while Meghan Markle swears by bodysuits to wear with skirts.

And it's not just the women who know styling tricks, the men are partial to them too. In fact, both Prince Harry and Prince William avoided a common wardrobe malfunction on their respective wedding days: sweat stains.

Both men wore military uniforms made from heavy fabrics, and while churches are often cold, it wasn't the case for them.

Not only were Westminster Abbey and St George's Chapel in Windsor packed with people, but there were also lights set up to film the ceremony, and they issued extra heat.

The solution? Sweat pads under the armpits to absorb any extra moisture.

Military tailors Kashket and Partners created Prince William's look, with company chairman Russell Kashket revealing, 'He was very aware of the heat factor in the Abbey because he knew all the lights would make it very hot. He said he didn't want to faint, so we made some minor adjustments to ensure his comfort and save his blushes.'

Penny grew up in France and studied languages and law at the Sorbonne Nouvelle University in Paris before moving to the UK for her MA in multimedia journalism at Bournemouth University. She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at MoneySavingExpert.com, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
