A rainbow of floral guipure-lace appliqués trails down the front and back of Mary Katrantzou's black Bayley gown, accentuating the figure-sculpting silhouette. Impeccably made in the UK from semi-sheer chiffon, it falls in a godet-panelled tulle skirt and is finished with a slip lining for coverage. A piece this spectacular needs little embellishment, so finish with a tonal knot clutch and barely there heels.
