The fashion world has lost a legend. Irish designer Paul Costelloe, a towering figure in both Irish and British fashion, has passed away at the age of 80. His death, announced by his family on Saturday, November 22, 2025, marks the end of an era for an industry he helped shape over decades. But here's where it gets emotional—Costelloe wasn't just a designer; he was a provocateur, a heritage champion, and a man who dared to challenge the status quo. His journey from Dublin to the global fashion capitals is a story of creativity, controversy, and enduring influence.
Costelloe's family shared that he passed away peacefully in London, surrounded by his wife and seven children, following a brief illness. They’ve asked for privacy during this difficult time, a request that underscores the intimate loss behind the public figure. Yet, his legacy is anything but private—it’s woven into the very fabric of fashion history.
Starting his career at the Grafton Academy of Fashion Design, Costelloe quickly ascended to the global stage, working in Milan, Paris, New York, and eventually London. In 1979, he launched his eponymous label, Paul Costelloe Collections, which became a staple at London Fashion Week for over 35 years. His designs were more than just clothing; they were a fusion of traditional Irish craftsmanship and modern elegance, often featuring Irish Linen and tweed—a nod to his roots that set him apart in an industry dominated by global trends.
But here’s where it gets controversial. In 1998, Costelloe made headlines for criticizing Irish women, claiming they lacked style. “Irish women have difficulty with style because it’s not in their inner nature… like the Italians,” he said. The statement sparked outrage, but it also highlighted his unapologetic approach to fashion and culture. Years later, he softened his stance, telling RTÉ in 2025 that Ireland had become “nearly too confident” and that Irish women were “very cool” with a “good sense of humour.” Was he right the first time, or did Ireland simply evolve? That’s a question still up for debate.
Costelloe’s most iconic collaboration began in 1983 when he was appointed personal designer to Diana, Princess of Wales. This partnership lasted until her tragic death in 1997, and it cemented his reputation as a designer of royal caliber. Yet, he remained grounded, working on accessible lines like his highly successful collaboration with Dunnes Stores, which brought his vision into homes across Ireland and beyond.
Even in his later years, Costelloe’s curiosity never waned. In a 2024 interview, he described himself as “still curious,” always exploring new ways to approach design. “I still think I’m a fairly good designer,” he said with characteristic humility. And this is the part most people miss—his ability to balance innovation with tradition, luxury with accessibility, made him a true pioneer.
As the designer behind the inaugural Ireland Fashion Week in October 2025, Costelloe’s impact was felt until the very end. His passing leaves a void, but his work—bold, thought-provoking, and unapologetically Irish—will continue to inspire. Did Paul Costelloe change fashion, or did fashion change him? Share your thoughts in the comments—let’s keep the conversation going about a man who never shied away from it.
