No matter the shade, the Princess of Wales never puts a foot wrong when it comes to her fashion choices.
However, it's undeniable that when Kate opts for an outfit in a bold red colour to attend diplomatic occasions and other high-profile events in the royal calendar, her ensembles are nothing short of spectacular.
Kate stepped out with her husband, Prince William, and other senior royals to attend the Commonwealth Day Service of Celebration at Westminster Abbey earlier this week wearing a coat dress by Catherine Walker paired with a matching hat by Gina Foster.

And with London looking somewhat grey due to a typical March forecast, Kate's pillar-box red outfit stood out even more...
The reasons why Princess Kate opts for red for stately engagements

Kate isn't afraid to wear any colour of the rainbow, but red is most certainly intentional.
Colour expert, personal stylist and fashion commentator Marina Thomas explains that Kate wears red at important and stately engagements for myriad reasons.
"The Princess of Wales often wears red to high profile events as did her late mother-in-law, Princess Diana.
"One reason Kate may be choosing to wear red is due to it symbolising courage, willpower and sacrifice," Marina told HELLO!.

"Wearing red certainly portrays confidence and a willingness to be seen and noticed."
In addition to wearing red to portray courage and confidence, Marina also notes that there are more sentimental reasons for choosing the shade.

"This is certainly a strong message Kate is either actively or subliminally choosing to send to the public: a message of unity, strength, and hope."

"I regularly have clients telling me they avoid wearing red due to their insecurities.
"This is, however, a huge shame, as it is the most versatile colour, it is the only colour that looks equally good on everyone."
As well as her outfit at the 2025 Commonwealth Day Service, Kate also wore a bright red coat on a visit to Wales, where she met local residents ahead of St. David's Day.

In 2024, she looked sensational in her go-to coat dress by favoured designer Alexander McQueen.
The red not only fitted perfectly with the themes of love, power and courage, as Marina explained, but was also in keeping with the festive season.
