Mary Katrantzou's penchant for vibrant colour shines through in the striped composition of this green, blue and grey organza Kahlo dress. Tailored in the UK and lined with black silk, it's shaped with exaggerated ruffles along the shoulders and a panelled halterneck bodice, then falls to an ankle-skimming hem. Adopt a more-is-more approach to styling with metallic stiletto heels.
