Long train top skirt in grenadine silk for a ball gown, richly decorated with a multitude of flowers au naturel, some worked in ombré. On the front, a spray of roses, peonies, anemones, daisies, foliage and their buds, with elegant scrolls of large roses worked in ombré on either side and above; graceful knotted ribbons holding a spray of flowers on either side. At the back, large, supple sprays of roses in full bloom and large irises, daffodils and dishevelled tulips, centaureas, daisies and umbellifers in their foliage. The lower edge of the skirt is adorned with a wide, laid-out frieze, masterfully echoing the ornamental style of the skirt as a whole. Dimensions: height in front: 105 cm, length from waist to bottom: 175 cm, circumference at bottom: 3.85 m, width at waist: 150 cm. (very good condition, discreet 5 cm restoration at the waist on the front of the skirt) The sumptuousness and richness of the design, as well as the finesse and exceptional quality of this ombré chantilly lace, indicate that it came from a very large workshop such as the Lefébure factory, either commissioned by a very high-ranking aristocratic family or produced as a centrepiece for a world exhibition.
