Meghan Markle dressed just like Princess Diana this weekend

Prince Harry and Meghan Markle celebrated their wedding anniversary this weekend with a special outing at the polo in California.

The Duchess of Sussex cheered on proudly as she watched her husband play, and looked every inch the royal in her monochrome outfit.

While some fans drew comparisons with Julia Roberts' character in Pretty Woman, it actually looked like she drew style inspiration from another royal: none other than her later mother-in-law, Princess Diana.

Meghan opted for white bermuda shorts by cult New York label Khaite, paired with a black and white polka dot pussy bow blouse. She rounded off her chic look with a black hat and oversized shades.

This very much reminded me of the black and white dotted dress Princess Diana wore back in 1987, to watch Prince Charles play a - wait for it - polo game, in Windsor.

While she didn't have a hat, and opted for pearl jewellery instead, I think you'll agree there are some strong similarities between the two looks.

Although Meghan's exact shorts are no longer available online, I've found some amazing alternatives for you to shop this summer.

This weekend marked Prince Harry and Meghan Markle's fourth wedding anniversary, after tying the knot in Windsor in 2018.

They are said to often have low key celebrations, sticking to hanging out at home and exchanging gifts based on anniversary symbols.

For example, the first anniversary is paper, so the Duchess had their wedding speeches framed. The fourth anniversary is fruit and flowers, which symbolize the blossoming of a relationship, and I'm sure the couple came up with thoughtful gifts.

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.
