Catherine, Princess of Wales, paid a visible stylistic tribute to her late mother‑in‑law as she cheered on England's Red Roses at their Women's Rugby World Cup match against Australia on Saturday.

The princess attended the group‑stage fixture at Brighton & Hove Albion Stadium in her role as patron of the Rugby Football Union wearing a black Alexander McQueen blazer, wide‑leg Roland Mouret trousers and a Cascade ruffle blouse by Knatchbull, an ensemble observers noted echoed a famous 1986 photograph of Diana, Princess of Wales, in a black trouser suit and white ruffled blouse.

The resemblance drew immediate attention online, where some royal followers described the outfit as a deliberate homage. The 1986 look, worn by Diana while meeting singer Bryan Adams in Vancouver, was by designer Jasper Conran; Conran later told The Telegraph that Diana was moving away from a "ballgown phase" and experimenting with sleeker, suit‑style silhouettes.

Accessories completed the princess's appearance: she carried a Chanel bag and wore a pair of Cartier earrings. Kate has previously referenced Diana in her wardrobe and jewellery choices, notably wearing a pair of earrings that once belonged to Diana at a VE Day service in May and often choosing to wear the late princess's sapphire engagement ring on public occasions.

On the field, England — ranked the world's top side — arrived at the match having recorded dominant wins earlier in the tournament, including a 69‑7 victory over the United States and a 92‑3 win against Samoa. The game against Australia marked the final match of the group stage; England are among the favourites for the tournament along with title holders New Zealand and Canada.

The princess, who succeeded Prince Harry as patron of the Rugby Football Union in 2022, appeared in good spirits in the stands as she supported the team. She and the Prince of Wales have both issued public messages of support to national teams in recent weeks: William posted in Welsh and English ahead of Wales Women’s tournament fixtures, while Kate sent a message wishing the Red Roses well as they began their World Cup campaign on home soil.

Catherine has long been associated with sport in royal engagements. She is patron of the All England Lawn Tennis and Croquet Club and a regular visitor to Wimbledon, has a background in tennis and hockey, and has taken part in a range of athletic activities at official events. Members of her family have also written about rugby's place in their upbringing; her sister, Pippa, has recalled planning family weekends around big matches.

Observers and commentators noted the public reaction to the princess's outfit, with some describing the look as "elegant" and others drawing direct comparisons to Diana's mid‑1980s tailoring. Royal watchers pointed to a broader pattern of nods to Diana in Catherine's public wardrobe and jewellery choices over the years, while the princess's appearance at a major home tournament underscored her continuing patronage of and interest in rugby.

The match and its attendant publicity come as the Women's Rugby World Cup progresses toward knockout rounds, with England positioned as a leading contender. Catherine's attendance reinforced the royal family's public profile at a high‑visibility sporting event and revived comparisons between two generations of royal women whose sartorial choices have often been noted alongside their public duties.
