Kate Middleton colour codes her luggage for this reason

It was revealed this week that Kate Middleton has a genius packing hack, and it's no surprise given the fact she normally travels to different countries several times a year on her royal duties.

And it turns out it's not the only travelling trick she knows. For example, her dresses have their own seats on the plane and she never wears this outfit when flying.

Now another one of her tips has surfaced online, and I have to admit it's pretty genius and oh-so-simple. You see the Duchess has so much luggage that she apparently colour codes them so she knowns exactly what clothes and other essential items are in which suitcase.

Tags are attached to bags and suitcases so staff can direct them to the right destination (see above picture). For example, blue tags are for the luggage that is needed on the plane, green for the hotel and yellow for when it's needed at a royal residence, say Balmoral or if the royals are staying at a foreign palace.

Each member of the royal family also has his or her own coloured tags, and both the Queen and Kate's are said to be yellow.

This way, nothing ever gets lost. Very handy.

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.
