For her visit to Fiji, she wore a statement dress quite different to the simpler ones she's worn before. The floral maxi is by New York brand Figue, which specialises in bohemian designs.
It featured a bright pink and blue pattern, balloon sleeves, tiered skirt and pom pom embellished belt - a nice nod to this season's Frida Kahlo trend.
The dress is definitely an investment piece at £1,200, however if you fancy it, it's still in stock on Net-A-Porter.
The Duchess styled it nicely with her favourite Castaner espadrilles and an embroidered bag.
Meanwhile, Prince Harry looked equally tropical with a blue short-sleeved shirt with palm leaf pattern.

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.
She's opening up about it *all*
