A woman's sack and petticoat of blue and pink striped silk twill, brocaded with flowers in shades of blue, pink, and green. The sack is open at the front with robings to the hem and elbow-length sleeves. There are two double box pleats at the back stitched at the neckline. The sack is made of two widths of silk, with partial panels on each side of the front. There is no waist seam; the skirts are pleated at the side back seam of the bodice, with a pocke opening in the skirt seams. The bodice front has an integral stomacher, one half on each side and meeting at the centre front. The bodice and sleeves are lined with unbleached linen. The bodice lining is in three parts. The fronts and back are one piece, open at the back; the opening boned and with worked eyelets for lacing. The stomacher fronts have separate linings, also boned, with eyelet holes, lacing to the back lining. A ruching of silk, with widespread pleats edges the front of the skirts, robings and neck in a straight line. The skirts have an additional gathered ruching arranged in a serpentine line.

The petticoat is made of 3 widths of silk, with a box pleat at the centre front waist and flat pleats at the sides and back. The waist is bound with blue linen tape, and fastens at the back. The petticoat is decorated with band of pleated ruching above the hem, and a deep gathered flounce above it.

Hooks and eyes were probably to the stomacher fronts and the petticoat waist for fancy dress in the late 19th century. The lining laces were probably replaced and padding sewn to the underarms.
