The Princess of Wales rarely puts a foot wrong with her outfit choices, and fares just as well with capsule wardrobe pieces as fabulous evening gowns. Case in point? The Gabriela Hearst Marley dress she wore to meet Sir David Attenborough back in September 2020. The classic denim midi dress wouldn't look out of place in her wardrobe today - or likely in 10 years time - and if you're looking for a similar timeless style, I've found a gorgeous one at M&S.

Browsing the new autumn/winter collection, I came across a denim dress that's perfect for the transitional seasons. It's cut in a regular fit with a flattering waisted shape and a row of buttons running from the neck down. It also features three-quarter length sleeves with subtle gathering at the shoulders and cuffs for a boho feel. And it even has pockets. The midi is made from 100% cotton, which means it's lightweight and breathable.

Retailing for just £40, it's available in UK sizes 6-24 and three different lengths. But you'll need to be quick - many sizes are now sold out.

The dress is getting so many five-star reviews from customers, with one writing: "Omg I absolutely love this dress, it's a great fit and looks amazing on. It's made from a lovely denim." While another called it "Perfect in every way!" adding "Was worried the sleeves would overwhelm me, but they’re great. The dress is a lovely weight, colour and fit."

HELLO!'s Lifestyle & Commerce Director Leanne Bayley is also a fan: "Shoppers IRL were flocking to this dress in store, which just goes to show the mass appeal of a M&S denim dress. The material felt nice and soft and most importantly, it wasn’t super heavy. What I love about this dress is that it can be instantly dressed up or down depending on the footwear you go for."

If your size is out of stock, M&S have just dropped a very similar denim dress that's also made from pure cotton and falls to a midi length. It features topstitched seams running through to the hem, creating the most flattering silhouette. Equally covetable, it retails for £48.

Kate styled her dress with heeled court shoes for the occasion, but I'd be more likely to wear mine with knee-high boots this season. M&S also made a case for styling theirs with ankle boots.

More recently, the royal proved her affinity for denim dresses once again as she was spotted in a surprisingly affordable number from H&M

The princess gave a rare glimpse into her life as she completed her chemotherapy treatment last year, sharing a personal family video with Prince William, Prince George, Princess Charlotte, and Prince Louis.

Shopping for a denim midi dress with a higher budget? I love this option from Reiss and it's just dropped in the sale.

The Terra denim dress features a classic shirt style with a collar and button-down front. It also has belt loops so you can cinch in your waist if you want to.
