Dublin-based Irish designer, Peter O'Brien, was born in London to Irish parents and returned to Ireland as a young child. On leaving school he worked in visual merchandising at Dublin department stores before leaving for London, aged 19. There he worked with Marshall & Snellgrove – now known as Debenhams.

On the advice of British fashion editor, Eve Pollard, to whom he had shown some sketches of his work, he successfully applied to Saint Martins School of Arts. He graduated with a 1st class honours degree in Fashion Design and then completed a post-graduate course at the prestigious Parsons School of Design in New York.

O'Brien next moved to Paris where he worked at Christian Dior, Givenchy and Chloé. In 1989 he was appointed creative director at Rochas where he remained for 12 years designing women’s wear and accessories, and overseeing menswear, perfumes and licenses.

O'Brien returned to Ireland in 2004 where he has since been working as a ready-to-wear designer as well as designing costumes for The Abbey and the Gate Theatre. In 2013, Peter was appointed costume designer on the film The Price of Desire which based on the life of furniture designer and architect, Eileen Gray.

Few Irish designers have obtained this level of success working with luxury international design houses whose origins are rooted in couture.

I am especially excited to partner with Dunnes Stores whose customers span three generations. I expect these pieces will appeal to women of all ages who appreciate a modern, classic style. The clothes are beautifully made in high quality fabrics- they will stand the test of time.
In Paris I learned that style is ageless and good taste is an attitude. This collection for Dunnes Stores is pared-down, graceful and theatrical.
