Sorry, All-Black—Kate Middleton Just Went Head-to-Toe in the Chicest Colour Trend of the Season
If the runways are anything to go by, then olive green is set to be the shade of the season. Read on to discover how Kate Middleton masterfully styled the trending neutral below.
There are certain celebrities I look to for very specific kinds of outfit inspiration.
If I need fresh ideas on how to style new-season trends, I’ll scroll through Elsa Hosk’s feed. When I want to update my wardrobe staples, I might turn to Jennifer Lawrence. But when it comes to mastering elegant, sophisticated dressing, no one delivers quite like Catherine, Princess of Wales. Almost inherently polished, Kate has perfected the art of refined styling. She pays close attention to fit and tailoring, often choosing clean lines and timeless pieces that exude elegance.
Meanwhile, her colour palette plays a huge part too; always poised, always considered. And this week, she earned extra points in my books by stepping out in a head-to-toe look that not only felt supremely chic, but also championed the colour trend fashion insiders are backing for the season ahead.
A hero shade across the autumn/winter 2025 runways—not to mention within spring/summer 2026 collections that have just wrapped at houses like Acne Studios, Hermès and Dior—the earthy olive green tone is actively establishing itself as a wardrobe staple.
Offering a refreshing alternative to the all-black ensembles so many of us default to in the colder months, this tonal hue feels just as easy to wear. Thanks to its subtle, grounded undertones, it layers beautifully within its own palette. Kate proved as much by pairing a sleek Victoria Beckham suit with a tonal green tee, nailing the art of colour drenching with her usual understated flair.
A longtime fan of tonal dressing, the Princess was spotted just last week in a head-to-toe grey look. But this week’s mossy green moment feels even more elevated; a sophisticated twist that reads as fresher and more fashion-forward than deeper neutrals.
More interesting than black yet just as versatile, take your colour-blocking cues from Kate Middleton this season and explore my edit of the best olive green pieces to shop right now.
