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 autumn/winter collection, I came across a new denim dress that's perfect for the transitional seasons. It's cut with a classic and elegant shirt silhouette and a row of buttons running from the neck down. It also features breezy short sleeves and a smart collared neckline. Falling to a midi length, it's made from 100% cotton, which means it's lightweight and breathable.

Retailing for just £46, it's available in UK sizes 6-24 and three different lengths. But you'll need to be quick - a couple of sizes are already sold out.

The dress is getting five-star reviews from customers, with one writing: "Stunning dress, only downside it is a bit tight around the bust, shame there was no elasticity in it, I’ve had so many compliments about it. Dress length was perfect. I bought size 18 petite and I'm 5ft".

And another said: "Really good quality denim dress in a flattering style. Fits well. Great price for the quality and design. Just love it!"

And another added: "I’ve been wanting this dress for ages. Good quality and beautiful style. Gave me 70s vibes."

If your size is out of stock, M&S have also dropped a corduroy dress with a similar vibe that I love. It's made from pure cotton and falls to a midi length. Featuring long sleeves with frill hems and a very flattering waisted silhouette, 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 ballet flats.

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.

If you're shopping for a denim mini dress instead, M&S has this one in the sale for just £23. Or if you're looking for a midi and have a higher budget, I love this option from Reiss.

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.
