Duchess Sophie's effortlessly stylish outfit is straight from Princess Kate's style book

Duchess Sophie has long championed British craftsmanship and it lies at the heart of her wardobe. And earlier this week, she proved once again why she's one of the Royal Family's standout style stars.

The 60-year-old sparked a royal frenzy as she visited Penelope Chilvers' Notting Hill boutique. The British label is one of her go-to labels and she cut an elegant figure in a rich brown Weekend Max Mara suit.

She paired the softly tailored Dilly jacket that she has worn on repeat with a new pair of fluid Zelma trousers, creating a relaxed yet refined silhouette.

Her look was completed by a sleek pair of Gianvito Rossi Foster 45 ankle boots in a trendy greige shade.

Royal fans were quick to praise Sophie's look and flocked to Instagram. "HRH looking very stylish," one wrote.

While another gushed, "HRH looks autumn-ready!". A third chimed in and admired how the warm brown tones complemented her blonde hair and sun-kissed complexion: "Love her suit with her blonde hair and tan."

With her mix of investment pieces and effortless polish, Sophie's look showed exactly why her style resonates with royal watchers.

Timeless yet quietly on-trend, with a nod to the brands she genuinely loves, and a subtle reminder of the heritage names that have shaped Princess Kate's own wardrobe too.

It comes as no surprise that Sophie carved out time in her busy schedule to pop into the boutique and with meet with Penelope Chilvers herself. The heritage brand is one of her favourites, with its classic boots and wedge espadrilles serving as a staple in her off-duty wardrobe.

Over the years we have seen her rock their tassel boots at the Royal Windsor Horse Show to cork wedges on summer walkabouts.

Princess Kate has been just as loyal, first stepping out in Chilvers's knee-high leather boots during her university days at St Andrews and still relying on them for country weekends, polo matches and Norfolk engagements nearly two decades later.

Both women also reach for other heritage heavyweights: Sophie in Barbour quilted jackets and bespoke Emilia Wickstead tailoring for public engagements.

And Kate in her long-standing favourites from Alexander McQueen, Burberry and Self-Portrait silhouettes.

Together they've cemented British heritage labels as the backbone of modern royal dressing, blending classic craftsmanship with a fresher, contemporary feel.
