Preen
Preen, by designers Justin Thornton and Thea Bregazzi, is one of Britain's hippest labels. The business started with a bijoux boutique on London's Portobello Road and over a decade later, the duo, who are partners in work and life, show their collection at New York Fashion Week and count Kate Moss and Gwyneth Paltrow among their many devotees. This season brings a vision of draped asymmetric dresses, structured skirts and floral print details.
