BANBRIDGE, NORTHERN IRELAND – June 15, 2026 – Thomas Ferguson Irish Linen, a luxury Irish linen weaver established in 1854, has announced the release of a collaborative linen collection developed with the late Irish fashion designer Paul Costelloe and his family. The collection represents one of the final original projects Costelloe worked on before his death in November 2025, with designs completed by the designer himself and developed alongside his son William and the Thomas Ferguson team. The range was woven in Ireland and photographed in part in Costelloe’s birthplace of Dublin.
The collaboration fulfilled an ambition Costelloe had pursued: producing a genuine luxury linen range in partnership with one of the last remaining authentic Irish linen weavers on the island. Rather than sourcing fabric internationally, the project was built around linen woven in Ireland at Thomas Ferguson’s mill, connecting Costelloe’s design vision directly to the heritage craft of Irish linen weaving that has been practised at the company since the nineteenth century.
Costelloe was actively involved throughout the project. The designs and core concepts were completed by the designer before his passing, and the collection was developed as a family effort, with Costelloe and his son William working side by side with the Thomas Ferguson team. Many of the photographs of the finished products were captured in Dublin, the city where Costelloe was born in 1945, lending the collection a personal connection to the designer’s Irish roots that defined much of his four-decade career.
Paul Costelloe was one of the most recognised names in Irish and British fashion. He served as personal designer to Diana, Princess of Wales, from 1983 until 1997, and was a fixture at London Fashion Week for more than four decades, as well as a presence at Ireland Fashion Week. Throughout his career, Costelloe consistently championed Irish heritage textiles, with Irish linen and tweed serving as recurring staples of his work. The collaboration with Thomas Ferguson reflects that lifelong commitment to the fabrics of his homeland.
For Thomas Ferguson Irish Linen, the collaboration continues a tradition of producing linen of a standard that has seen the company’s fabric featured in major film and television productions, including work for HBO, Netflix, Disney, and the BBC. As one of the last true Irish linen weavers operating on the island of Ireland, the company occupies a distinct position in a craft that has largely moved offshore, making its partnership with Costelloe a meeting of two custodians of Irish design heritage.
“This collection carries a special meaning for everyone involved. To have worked alongside Paul and his family on one of his final projects, weaving linen here in Ireland for designs he completed himself, is a profound honour. We hope it stands as a lasting tribute to his vision and his lifelong love of Irish cloth.”
Following Paul Costelloe’s passing, his children have taken over the management of the family fashion company, continuing the legacy he built over more than forty years. The collection developed with Thomas Ferguson stands among the final original works the designer personally created. Further information on the Costelloe fashion house is available at costelloe.com.
