Gabriela Hearst references Costa Rican singer Chavela Vargas’s traditionally patterned ponchos as inspiration for the label’s Resort 2019 collection, which includes this black Mariano dress. It’s patterned with a white geometric print which is accented with red stripes, and is shaped to a figure-skimming silhouette that can be defined with the matching belt at the waist. Style it with white accessories for a smart lunchtime event.
