Preen by Thornton Bregazzi showcased five looks in graphic two-tone prints at its Resort '19 presentation, and this 'Helen' asymmetric dress is one of our favorites. It's softly draped from devoré silk-blend satin that's patterned with an abstract sky-blue and red leaf motif. The coordinating slip means you won't need to worry about finding the correct underpinning. Style yours with optic white boots.
