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-in collection at M&S, I came across a denim dress that's ideal for the transitional seasons. It's cut with a classic shirt silhouette and a row of buttons down the front.

It also features breezy short sleeves, a collared neckline and a self-tie belt that cinches the waist, so you can adjust the silhouette to how you like it. Falling to a midi length, it's made from 100% cotton, which means it's lightweight and breathable.

Retailing for just £46 (or $90.99 if you're in the States), it's available in UK sizes 6-24 and three different lengths. It has glowing reviews, with one writing: "Comfy, flattering and easy to wear - perfect to dress up or down. Excellent quality." 

Another said: "Beautiful style and fit. I bought the tall and being 5ft 10 it was a perfect length. Lovely denim material, not too thin." Several people said it runs large so it could be worth sizing down.

Kate styled her dress with heeled court shoes for the occasion, but I'd be more likely to wear mine with knee-high boots or sling-backs and a rattan bag as the weather gets warmer.

The royal proved her affinity for denim dresses once again as she was spotted in a surprisingly affordable number from H&M back in 2024.

The princess gave a rare glimpse into her life as she completed her chemotherapy treatment, 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, I love this one from M&S. Or for a spring-ready midi, M&S also just dropped this puff sleeve denim midi dress. It gets glowing reviews from customers who say it's "very flattering" and "high quality".

If you have a higher budget, I love this chic zip-up style from Boden.
