This is where you've seen Kate Middleton's mint dress before

Just a few days after wearing a bold dress at a Buckingham Palace garden party, Kate Middleton is at it again. This time though, the Duchess of Cambridge has opted for a more subtle hue for another event at the palace.

If you think it looks familiar, that's because she has worn it before, during the 50th anniversary of Prince Charles's investiture in 2019.

The dress is by one of her favourite designers, Emilia Wickstead, and features a high neck, button-down blouse top and floaty midi skirt.

It's in fact not too dissimilar to the green Self Portrait dress she wore to meet with schoolchildren at Sybil Strachan Primary School in the capital city of the Bahamas, Nassau.

The Emilia Wickstead gown was created back in 2019, so you unfortunately can't buy it anymore, however I've found some affordable options for you below, which are quite similar.

The Duke and Duchess of Cambridge were joined by Prince Edward and Sophie Wessex as they mingled with guests in the gardens of Buckingham Palace, with Kate braving the rain with a chic umbrella that subtly matched her dress.

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.
