Justin Thornton and Thea Bregazzi first set up shop together in London's infamous Portobello Road in 1997, to house their recently launched but already cult, fashion line Preen. Characterised by innovative structure and ultra-modern design, Preen has become a go-to label for a hip use of print and occasion wear - with pixelated hues and sheeny fabrics in cute tailored dresses and sharply cut blazers. As well as dressing London's finest from Kate Moss to Sienna Miller, the label is worn by Hollywood's red carpet royalty, from Carey Mulligan to Gwyneth Paltrow - girls who like their glamour with a hint of edge.
