The significance behind the outfits in that royal family portrait

To celebrate Prince Charles' 70th birthday this year, Kensington Palace has released a sweet family shot of the Prince of Wales surrounded by his children and grandchildren.

The shot includes Prince Charles and Camilla, Harry and Meghan, William and Kate, as well as their children Louis, Charlotte and George, and was taken by photographer Chris Jackson Getty in the garden of Clarence House.

But whilst you were distracted by Prince George's cheeky antics, you might not have noticed the significance behind some of the outfits.

First off, everyone wore blue, a bit like when they matched the Queen's outfit during Trooping The Colour, which shows unity and trust as a family.

The Duchess of Sussex and the Duchess of Cornwall, which shows positivity too, like they are all embracing this new chapter in the royal family history.

Princess Charlotte also wore the same Pepa & Co dress she wore at Trooping the Colour, a clear sign that her mother is teaching her about sustainability by wearing outfits more than once.

And finally, little Prince Louis a La Coqueta romper which is very similar to one that Prince William wore in a picture with Princess Diana over thirty years go.

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.
