Rocha moves to Ireland after graduating from the Croydon School of Art, London. Known for his hand-crafting, beading and appliqué to garments, he first establishes a name for himself with his Chinatown label in Dublin in the 1980s and later designing clothing for both men and women in the Irish high street stores A Wear and their luxury stores Brown Thomas. He designs a range of cut crystal stemware and vases for Waterford Crystal in collaboration with glass designer Marcus Notley, until that firm’s closure in 2008. The brand relaunches in 2010 and Rocha’s crystal product ranges become available again.
By 1993, Rocha is named Designer of the Year at the British Fashion Awards. He runs his own “John Rocha,” “John Rocha Jeans,” “Rocha John Rocha” and “John Rocha Jewellery” labels alongside a diffusion clothing, homeware and accessories label for the department store Debenhams. He also designs the interiors of the Morrison Hotel in Dublin and the Orion Building in Birmingham. He is awarded the ‘Special Award’ at the Ernst & Young Irish Entrepreneur of the Year Awards 2008 which takes place in the City West Hotel in Dublin on October 23, 2008.
Rocha continues to produce a ‘pret-a-porter’ womenswear and menswear range which he showcases twice annually at the British Fashion Council sponsored London Fashion Week (February & September). His John Rocha lifestyle boutique opens on Dover Street, London, in 2006. His design business, operating as Three Moon Design, is located at Dublin’s Ely Place with a turnover of €200 million per year.
In 2014 Rocha showcases another Spring/Summer collection at London Fashion Week and announces his retirement from the event, stating, “At this point in my life I want to live by my calendar and not the Fashion Week calendar. Stopping allows me to do that.”
Rocha is made a Commander of the Order of the British Empire (CBE) in 2002 for his contributions to the British fashion industry. In April 2015 he is awarded the Outstanding Achievement in Art & Design at The Asian Awards.
In 2010 Rocha is one of six contemporary, internationally renowned Irish fashion designers featured on a set of Irish postage stamps issued by An Post. The other designers featured are Paul Costelloe, Louise Kennedy, Lainey Keogh, Philip Treacy and Orla Kiely.
