The gown was crafted from a vibrant pink fabric, featuring a ruched collar and black velvet trim, as well as double-strap cuffs and a matching belt. Catherine carried a black velvet clutch from JIMU that matched the dress. She wore her favourite black velvet pumps by Jimmy Choo, adding a touch of elegance to the outfit. Her Twisted Circle drop earrings from UK retailer Accessorize added a subtle sparkle, crafted from 100% brass.

Catherine styled her hair in a chic ponytail, creating a polished look that shone throughout the evening. Many fans noted that her bright pink polka dot dress resembled a dress worn by Princess Diana in 1983. Diana's similar dress featured a high neck and polka dots, which she wore to the UK's Variety Club luncheon and later in Australia that same year.

Catherine's choice could be seen as a touching tribute to Diana, honoring her late mother-in-law even though she never met her before Diana's tragic death in 1997. Catherine continues to honor Diana's legacy, especially in fashion, by wearing dresses that reflect Diana's timeless style while adding her own modern twist. This is not the first time Catherine has taken inspiration from Diana.

Last year, during a visit to NHS staff and patients, she wore a blue polka dot Alexander McQueen dress reminiscent of Diana's outfit during her 1989 trip to Kuwait. This highlighted Catherine's commitment to honouring Diana through fashion. The royal couple visited Ireland at the request of the Foreign and Commonwealth Office to highlight the close links between the UK and Ireland.

Catherine's impeccable style contributed to the success of the event, where she also charmed guests with her radiant smile. One foreign minister shared a heartwarming story about his children writing to Prince George, Princess Charlotte and Prince Louis, inviting them to visit Ireland in the future, which brought laughter and applause.
