Why Princess Eugenie can't wear a tiara (but might be allowed to on her wedding day)

The royal family love their tiaras, and a wedding look wouldn't be complete without one. Kate Middleton's Cartier wedding tiara was an important heirloom, while Meghan Markle also borrowed hers from the Queen.

But while Meghan and Kate are allowed to pimp their gowns with the accessory as much as they like, Princess Eugenie isn't officially allowed to - yet.

According to ancient royal protocol, women aren't allowed to wear tiaras during the days, just for an evening do, and they are reserved to married women.

Which is why Princess Eugenie technically can't wear one on her wedding day (and Fergie didn't wear a wedding tiara), however this is likely to be waved as it was for both Kate and Meghan, and in fact any other royal bride.

Etiquette expert Grant Harold told the BBC, 'Flashy diamonds and tiaras are not worn during the day, and only married ladies wear tiaras. For married ladies it was a sign of status and would show you were taken and not looking for a husband.'

He continued, 'For the gentleman it was a clear sign not to make advances toward the lady in question.'

Well if a princess can't wear a tiara on her wedding day, something's not right.

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.
