Originally founded as a Notting Hill boutique in 1996, Justin Thornton and Thea Bregazzi launched Preen by Thornton Bregazzi to tap into their darkly romantic aesthetic. The British duo are known for mixing elegant, vintage-inspired fabrics with deconstructed craftsmanship – think asymmetric hemlines and ruching. Look to the brand for dresses and separates that exude an unabashedly punk-meets-glam vibe.
