Though they first met at the age of 18, Justin Thornton and Thea Bregazzi did not begin designing together until they worked on a collaboration with British designer Helen Story in 1996. Shortly after that project, the duo launched Preen by Thornton Bregazzi, a collection of one-off pieces sold from a tiny boutique on London’s famed Portobello Road. Today, Preen by Thornton Bregazzi dresses are celebrated for their signature eclectic charm with a modern twist.
