Preen is a fashion label formed by British designers Justin Thornton and Thea Bregazzi. They first designed together when asked by Helen Storey to consult on her autumn/winter 96/97 collection. Inspired by this experience of designing together, they launched Preen. Now Ppreen has a clientele consisting of f.e. Kate Moss, Amy Winehouse, Linsday Lohan and the Arctic Monkeys.
