To start off her day in Northern Ireland, the Queen debuted a stylish new coat dress by renowned designer Bruce Oldfield, who had also designed her Coronation gown the previous year.
Contrary to other options in her wardrobe, the Queen chose a new outfit for the occasion, opting for a coat dress with leaf-like velvet appliqué patches.
Oldfield revealed that the outfit was originally intended for Christmas Day but was repurposed for the St.
Patrick's visit.
The velvet appliqué patches were a modern interpretation of a classic Rococo leaf motif, elegantly crafted to impress Her Majesty.
Accessorizing the coat dress, the Queen donned a diamond and turquoise clover brooch, symbolizing unity between Northern Ireland and the Republic of Ireland.
She also added a pale green silk scarf, a beloved accessory of hers.
Later in the day, the Queen changed into a second outfit designed for a World Poetry Day event, wearing a bottle-green dress by Anna Valentine and an Art Deco-style emerald brooch.
The color green, in addition to its Irish connection, was believed to give the Queen strength and composure in her royal duties, projecting an image of warmth and approachability.
By showcasing two looks in the same hue and carefully selecting jewelry, the Queen reaffirmed her commitment to the art of diplomatic dressing, a tradition upheld by modern members of the Royal family.
Over the years, Queen Elizabeth had used fashion to express solidarity and respect during visits to both Northern Ireland and the Republic of Ireland, often incorporating symbolic elements in her attire.
Similarly, other members of the Royal family have followed suit in employing diplomatic fashion choices during international visits.
From Princess Diana's bold Ireland-themed outfits to the Duchess of Sussex's bottle-green ensemble in Belfast, each outfit has carried its unique significance in conveying respect and appreciation.
This tradition of diplomatic dressing extends beyond Ireland, with examples of the Royal family coordinating their attire to honor various countries and events worldwide.
In a world where the Royal family's actions often make headlines, the consistency in their diplomatic fashion choices serves as a reassuring nod to their commitment to diplomacy and tradition.
