Irish fashion designer Paul Costelloe has died in London aged 80. His family reported that he passed away peacefully, surrounded by his wife and seven children after a short illness.

Costelloe is celebrated as a key figure in both British and Irish fashion, famously serving as the personal designer to the late Diana, Princess of Wales. His work often featured traditional Irish fabrics like linen and tweed, creating a unique and recognizable style.

He launched his own label, Paul Costelloe Collections, in 1979, showcasing his designs at prestigious events, including London Fashion Week, Paris, Milan, and New York. In 1983, he began his collaboration with Princess Diana, which continued until her death in 1997.

Despite facing criticism in 1998 for comments on Irish women's style, Costelloe maintained a commitment to elevating Irish fashion on the global stage. Reflecting on his life, Taoiseach Micheál Martin shared condolences, stating that Costelloe had elevated Irish fashion to the global stage.

His passing marks the end of an era for fashion lovers, as he leaves behind a legacy that profoundly shaped modern Irish fashion.
