Princess Catherine’s Style Evolution Sparks New Comparisons to Princess Diana After Departure of Longtime Aide

For years, the wardrobe of Catherine, Princess of Wales has been closely associated with elegance, modernity, and carefully curated royal style. But since the departure of her longtime aide Natasha Archer, royal fashion watchers have noticed something interesting: a growing number of outfits that appear to echo the timeless looks of her late mother-in-law, Diana, Princess of Wales.

Archer, who worked alongside Catherine for more than a decade, was widely believed to have played an important role in shaping many of the Princess’s signature fashion choices. Although never officially described as her stylist, she became a trusted figure whose influence could be seen in Kate’s polished, contemporary looks.

Since Archer’s departure, however, observers have noticed a subtle shift. Rather than introducing a completely new direction, Catherine appears to be drawing inspiration from one of the most iconic royal dressers in history — Princess Diana.

A Familiar Shade of Blue

One of the clearest examples came during Trooping the Colour 2026. Catherine stepped out in a pale blue coat dress designed by Catherine Walker, paired with a wide-brimmed hat and white pumps.

The ensemble immediately reminded royal fans of Princess Diana’s Easter Sunday appearance at Windsor Castle in 1987, when she wore a remarkably similar duck-egg blue Catherine Walker outfit. Although nearly four decades separate the two appearances, the resemblance was striking.

Revisiting Diana’s Signature Details

Fashion historians point out that Diana popularized many elements that remain timeless today: power dressing, tailored jackets, statement collars, and feminine silhouettes.

In recent months, Catherine has worn several ensembles that seem to pay tribute to those styles.

A black trouser suit paired with a white ruffled blouse in 2025 drew comparisons with one worn by Diana during a gala in Vancouver in 1986. Likewise, a cream skirt worn during Catherine’s visit to Reggio Emilia, Italy, last month resembled one Diana wore with a Catherine Walker jacket in 1989.

The similarities don’t appear to be exact replicas. Instead, Catherine often modernizes the looks, adapting them to contemporary tastes while maintaining subtle nods to Diana’s fashion legacy.

The Return of Statement Collars

One style forever associated with Diana is the statement collar. Throughout the 1980s and early 1990s, the Princess frequently wore dresses featuring lace, pie-crust collars, and Peter Pan details.

In late 2025, Catherine appeared in a black-and-white Alessandra Rich dress whose prominent collar immediately brought back memories of Diana’s memorable Gina Frattini dress from 1981.

Modern Touches With Diana-Inspired Colors

While Diana generally preferred skirts and dresses, Catherine has embraced suits more frequently. A beige Roland Mouret suit she wore earlier this year shared similarities with Diana’s beige linen ensemble from 1997.

Another recurring theme has been the Prince of Wales check pattern. Diana wore a double-breasted checked suit in 1997, and Catherine has repeatedly incorporated similar patterns into her wardrobe, most notably through a Bella Freud suit. Some observers view this as both a tribute to Diana and a subtle nod to Prince William’s title.

A Tribute Rather Than an Imitation

Royal fashion experts emphasize that Catherine’s recent style choices are less about copying Diana and more about honoring her influence. Princess Diana transformed royal fashion and remains one of the most recognizable style icons in history.

By blending classic inspirations with modern tailoring, Catherine continues to create a distinctive image of her own while acknowledging the legacy of the woman who forever changed the face of royal fashion.
