Gabriela Hearst's shirt dress is named Cheval, which translates from French as 'horse' – the designer grew up on an Uruguayan ranch and is passionate about horseriding. It's crafted in Italy from soft cashmere with cropped balloon sleeves and has a belted waist to cinch in the relaxed fit. Wear it with Louboutin pumps, a Christian Sirano handbag, and matching jewelry.
