"The dress is constructed with a cap sleeve, high neckline and features a corseted bodice with draping to the front and a heart-shaped detail at the back," said Deacon. "The bespoke silk cotton lace was hand appliquéd to create an illusion of the dress having 'no seams'. The lace bodice is embroidered with pearl detailing over an organza and tulle underskirt, which has layer upon layer to enable a floor-sweeping movement. It's a privilege to show the craftsmanship that my team produces in London and a real testament to Pippa's support of British fashion."
