You don't need me to tell you that when a royal steps out in an outfit, it's pretty sure to sell out fast. Just a couple of recent examples include Meghan Markle's white mini dress and Kate Middleton's L.K.Bennett dress which was so popular, it got re-issued over a year later.

Now the Duchess of Cambridge has stepped out in yet another fabulous - and more or less affordable - dress, and it's flying off the shelves again.

Kate, who is the Patron of the Royal College of Obstetricians and Gynaecologists, visited the headquarters of the Royal College of Midwives and the Royal College of Obstetricians and Gynaecologists to hear about the ways they are working together to improve maternal health care, ensuring women are receiving the safest and best care possible at one of the most significant times in their lives.

For the occasion, she chose another Self Portrait dress - the green one she wore earlier this month is still available below - this time a cream blazer dress featuring an embroidered bodice and belt to cinch the waist.

Bouclé is a fabric favoured for its smart classic look, but at the hands of Self-Portrait's Han Chong it receives a contemporary twist, as evidenced by pieces like this midi dress. Promising to make a striking but sweet entrance, it boasts a neatly tailored jacket to the bodice – complete with a waist-cinching adjustable belt – before giving way to a chiffon pleated skirt trimmed with lace for the romantic finish you’d expect from the label.

This natural pearl is teamed with a gold vermeil chain for maximum impact. Monica Vinader is a sustainable jewellery designed beloved by Kate.

She teamed it with matching pumps and a clutch bag, as well as a delicate pearl necklace and pearl earrings by Monica Vinader, which you can shop above too.

Kate put her own spin on the dress as it actually comes with a brown leather belt, which she swapped for a cream one to match the rest of the outfit.

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.
