Preen By Thornton Bregazzi Womens Silk Multicolor Black Abstract Print Dress XS. Preen by Thornton Bregazzi Brought together by a shared love of Victoriana, Justin Thornton and Thea Bregazzi launched Preen to instant success in 1996. Romantic but contemporary, their collections are worn by Kate Bosworth, Michelle Obama and Scarlett Johansson. We love the label’s universally flattering dresses and fresh use of color and pattern.
