The lace bodice of Matthew Williamson's dress is designed to resemble the wings of a swallowtail butterfly – hundreds of sequins have been hand-applied to outline this intricate pattern. This piece is finished with alternating tiers of glimmering silver beads and plumes of feathers . The silk slip lining ensures a smooth fit.
