Princess Diana made this present faux pas for her first Christmas with the royals

As you might expect, Christmas in the royal family is a pretty big deal that is steeped in tradition, from what they eat for their Christmas dinner to what they wear during the many celebrations (remember, no diamonds before 6pm).

But they also have little, more unexpected traditions that are much less stuffy than what protocol dictates. At 6pm on Christmas eve, they all exchange presents, but the rule is that they have to be joke ones, cheap and cheerful, because let's be honest, when you have everything already, what else could you possibly need.

So last year for example, Prince Harry got the Queen a shower cap, and Kate Middleton reportedly once got Prince Harry a grow-your-own-girlfriend kit - pre Meghan Markle of course! And Meghan apparently gave the Queen a singing hamster on a string last year.

However one royal who didn't get the memo, for her first Christmas with the royals at least, was Princess Diana. According to Reader's Digest, in 1981, the newlywed apparently gave Princess Anne a lovely cashmere sweater, and in return she got a toilet roll cover. Chic.

Diana had a good sense of humour though, so she quickly recovered, buying a leopard-print bath mat for Fergie the following year.

With Christmas round the corner, we can't wait to see which presents they get this year.

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.
