Kate Middleton Rocks A Classic Fall Color With The Perfect Autumnal Outfit For Women Over 40

Kate Middleton was once again photographed in a look we need to copy. Ever since the early aughts, when Kate began her relationship with Prince William, the Princess of Wales has been known for her preppy and sophisticated fashion. Simple silhouettes and classic, timeless fabrics have been a staple in the royal's wardrobe, as Kate slowly but surely became a fashion icon over the years. Seeing the subtle changes in her fashion choices has been inspiring, as Kate Middleton's style has also transformed since her cancer diagnosis, which was made public in 2024. A year later, the royal announced that her cancer was in remission, and with that, she was ready to continue her royal obligations. In September 2026, Kate was photographed during a visit to the Isle of Bute in Scotland alongside Prince William, and as the two walked around the community, all we could think of was how perfect Kate's fall outfit was.

Kate was comfortable yet chic in a pair of brown skinny jeans tucked into matching brown suede boots and an olive green turtleneck sweater — a fall staple. In fact, pairing it with a turtleneck is an easy way to style your favorite trench coat, which is exactly what Kate did. The royal donned a classic brown Burberry trench coat, the perfect jacket choice for early fall. The Princess of Wales finished the look off with a statement belt and a green newsboy hat, which she put on as the weather got colder throughout the day.

Kate, who turned 44 in January 2026, has shown just how simple and stunning fall fashion for women in their 40s can be. By combining classic fall pieces in earthy colors, the royal created a timeless look that will undeniably serve as fashion inspiration for years to come, regardless of what the runways dictate.

Earthy tones are always back in style for fall, and this year, brown is definitely the new black. And while brown clothing can mesh with any color, it looks particularly fab with various shades of green. Kate Middleton clearly couldn't agree more, as the royal has been loyal to the color combo for years. In September 2025, Kate wore a brown Ralph Lauren skirt and a green suede jacket by the brand ME+EM while meeting First Lady Melania Trump in Windsor, England. The royal accessorized the look with brown boots and a green scarf, staying within the color palette.

"Most people think brown and green are 'too earthy,' 'too muted,' or just plain hard to style together. But the truth is, when used intentionally, this combination is incredibly chic and surprisingly versatile," personal stylist Shannan Allen shared on Instagram. "Brown is a grounding neutral — rich, warm, and understated. It creates a strong base for building a look," she explained, adding, "Green brings depth and variation; whether you choose olive, sage, emerald, or forest, it adds contrast without overwhelming." So, when in doubt, brown and green are a perfect choice for looking stylish at any age as the colder weather approaches.
