Opt for a louche outer layer in the form of Gabriela Hearst's Llorona cardigan, which comes in a satisfyingly slouchy longline silhouette. The finely ribbed style has been crafted from pure cashmere, rendered in an eternally appealing camel colorway. The New York label has made its name producing impeccable knitwear designs, and this piece is no exception. Drape it over ensembles in coordinating hues.
