The major fashion rule that Kate Middleton ignored at the England vs Wales rugby game Prince William and Kate Middleton attend clash at Principality Stadium in Cardiff Read more: Kate Middleton 'misses family milestone' to cheer on rival sides of Six Nations clash with Prince William By JO TWEEDY FOR MAILONLINE Published: 09:19 GMT, 16 March 2025 | Updated: 09:59 GMT, 16 March 2025 The Princess of Wales cut an ever stylish figure while cheering on England yesterday afternoon alongside Prince William on the final day of the Six Nations at the Principality Stadium in Cardiff. Throughout her royal life Catherine, 43, who is patron of the Rugby Football Union (RFU) and looked delighted by the England rugby team's emphatic win over Wales, has been partial to donning a military-style coat - particularly at more ceremonial royal occasions. And yesterday, the mother-of-three, who posed with members of the crowd for selfies after the team's 68-14 trouncing of Wales, opted for a double-breasted one in timeless navy, with shiny gold buttons on the cuffs and front. However, there was one long-held fashion rule that Catherine Middleton appeared to ignore - by teaming the coat with a black turtle neck, bag and boots. The coupling of black and navy in the same outfit has sometimes been considered a sartorial no-no in fashion circles as two dark shades are thought to be too competing. The Princess of Wales teamed the coat with black suede knee-high leather boots, a co-ordinated black leather clutch bag and wore her long hair loose at the match, which didn't see England win the Six Nations but did see them come a close second to France. While fashion fans have long declared black and navy in the same ensemble a fashion mismatch, the Princess of Wales showed just how good it can look. Meanwhile, Prince William showed his allegiance to his royal title by donning the red of the Welsh flag in a snug-looking scarf with a navy overcoat that complemented his wife's look.

While the rivalry on the pitch was long-standing and deep-rooted between the two sporting squads from either side of the Severn Bridge, the competition between Prince William and Princess Catherine was likely more friendly in nature. In what could be construed as a show of friendship in the sport, the couple sat between Rob Udwin, president of England's RFU, and Terry Cobner, president of the WRU, with both royals positioned next to the head of their respective patronage. And while Catherine was spotted beaming as the English side dished out a record-breaking score, empty seats began to emerge across the venue, which holds 74,500 people, as soured Welsh fans could no longer bear the brunt of their loss. Echoes of 'Swing Low, Sweet Chariot' roared in the Welsh capital as the English side closed out the game with another try, leaving Welsh fans disappointed following a less than fruitful Six Nations performance. While Catherine beamed following the win, Prince William appeared more sombre as he donned his bright red scarf matching same the shade as the strip worn by the Welsh rugby team.

They then headed to the pitch to meet Rodrigo Gonzalez, co-founder and co-chief executive of 2022 Earthshot Prize winner Notpla, to mark the rollout of its plastic-free food packaging across Welsh Stadiums. Ahead of the match, the Prince and Princess of Wales met injured players who are supported by the Welsh Rugby Charitable Trust. The royals chatted with injured players inside the Sir Tasker Watkins Suite, a space at the Principality Stadium which is dedicated for use by the players and their families ahead of matches. The beaming couple looked animated as they spoke to injured players - both in overcoats for the chilly Cardiff weather - which sat at a chilly 7C - before taking their seats for the match. William is patron of the Welsh Rugby Charitable Trust, which was set up to help players who have been severely injured while playing rugby in Wales, and their loved ones, inviting them to every Wales home game and hosting an annual family day. They officially opened the suite, named after a former Welsh Lord Chief Justice and World War II veteran who was later president of of the Welsh Rugby Union, prior to attending England and Wales' previous Six Nations clash on February 25. Catherine took over the role with the RFU from her brother-in-law Prince Harry in 2022, who was forced to give up the patronage as part of the Megxit agreement.

Rob Udwin and Catherine were all smiles as England continue their strong lead on Wales, whilst Cobner and William appeared dejected BREAKING NEWS Kate and William share sweet moment at Commonwealth Day service as she returns to the event The Princess of Wales, who grew up watching rugby with her family, is known as one of the sportiest members of the Royal Family, and has gamely taken on her husband in everything from dragon boating to wind buggy racing at royal engagements. She has played tennis and hockey from a young age and is already royal patron of the All England Lawn Tennis and Croquet Club and is a frequent visitor to the Wimbledon Championships. While her love and passion for hockey has been well publicised, less well known is her family's love of rugby. Her sister, Pippa, wrote in Vanity Fair magazine in 2014: 'Rugby was a big thing for our family, we'd plan our weekends around the big matches.' In the Daily Mail's Palace Confidential podcast, Jo Elvin joked that the Wales family 'may need a referee in house' for the game - which forms part of the Six Nations Championship. It's unclear whether the royal children - Prince George, 11, Princess Charlotte, nine, and Prince Louis, six - are also split on which team they support: Wales for William, or England for Catherine. In fact, on Mike Tindall's podcast The Good, The Bad and The Rugby, Prince William did joke that the question of which team the children support has become 'quite the thing' at home. He said: 'It's become quite the thing in the house. [Catherine] is quite into it. I'm trying to stay out of it.'

It's thought that George, Charlotte and Louis watched the game at their home in Windsor. Catherine is gradually returning to public duties after revealing she is in remission from cancer. She is also set to appear at an engagement with the Irish Guards on St Patrick's Day in London on Monday. William's love of various sport has also been well-documented, famously, a huge fan of Aston Villa after being taken to matches as a youngster. He told the BBC in 2015 that he didn't want to follow 'run of the mill teams' such as Chelsea and Manchester United like his classmates. The Prince, who is also patron of the Football Association, told the broadcaster: 'I wanted to have a team that was more mid-table that could give me more emotional roller-coaster moments.' William has also been showcasing his respect and love for Welsh culture in his role as the Prince of Wales whilst delivering his St David's Day message entirely in the country's native language on March 1. He revealed last year that he had been using Duolingo to practice whilst on the go since he was named Prince of Wales in 2022 the death of his grandmother Queen Elizabeth II.
