Princess Kate has attended the annual Irish Guards St Patrick's Day Parade at Cavalry Barracks in Hounslow nearly every year since she married Prince William in 2011.
With some exceptions, including the impact of the Covid-19 pandemic, the Princess of Wales, 44, has pulled out the stops every year for a glamorous green look to celebrate the occasion.

The royal has been spotted enjoying the festivities by presenting the Irish Wolf Hound regimental mascot of the Irish Guards with a sprig of shamrock before a swig of Guinness with her husband.
We've been reminiscing over her back catalogue of glorious St Patrick's Day looks - and can't wait to see what she chooses this year. Take a look at all her best sartorial moments....

Princess Kate made a triumphant return to the 2025 celebrations in a glorious green coat and matching shamrock-inspired hat. Proving that she's the queen of method dressing, her smart forest green ensemble was absolute perfection.
She finished the look off with her beloved Grace Han handbag and wore her brunette tresses swept into a chic chignon.

Last year, the Princess wowed in a teal coat dress with a structured bodice and a straight-cut skirt. The piece featured padded shoulders, a high neckline, and covered buttons down the front. The cinched number was styled with a pair of coordinating suede heels and a gorgeous fascinator.

In 2022 the royal opted for a deeper shade of green in her wool coat dress. The garment featured military-style epaulets, as well as a sharp collar and a belted waistline. She accessorized the look with a low bun and hat, as well as suede stilettos.

In 2021 the Prince and Princess delivered a video message to mark the occasion along with other world leaders due to the COVID-19 pandemic. Kate rocked an apple green tweed blazer and wore her brunette locks down for a feminine look.

In 2018 the royal was pregnant with Prince Louis. The new mum-to-be styled a fur-adorned bottle-green coat with a felt hat, black stockings, and black block heels.

No St Patrick's Day appearance in 2016 meant that Princess Kate had to pull out all the stops this year. She looked impeccable in a pine green coat with gold double-breasted buttons down the front and a velvet collar and matching cuffs. She wore a new hat for the occasion and popped on her go-to green suede heels.

2015 was the year that Kate broke from tradition. The Princess was pregnant with Princess Charlotte at the time and wore a bump-flattering chocolate brown A-line coat dress with platformed heels in the same hue and a felt hat.

In 2014 Kate rocked a flattering fit-and-flare coat with a leather croc belt and platform heels. Her hair was worn in a soft layered blowdry to accommodate her bow detail hat.

In 2013 the then-Duchess wore a simple emerald green coat dress with a V-neckline revealing a black roll-neck jumper underneath. Kate tied the look together with opaque black tights, black heels, and a black flower-adorned hat.

The year after her wedding the then-Duchess of Cambridge made her St Patrick's Day debut in a green belted blazer dress with unexpected brown accessories.
