A woman's sack and petticoat of yellow silk, figured with white in floral motifs and brocaded in floral motifs with maroon, pink, green and yellow silks. The sackis open at the front, with robings to the hem, and elbow-length sleeves with triple, pinked and scalloped sleeve ruffles. The sleeves are lined with bleached linen. At the back are two, double box pleats stitched at the neckline. The sack is made of 4 widths of silk, with a partial panel on each side of the front. A waist seam runs from the front edge to the side-back seam; the skirts are pleated either side of the pocket openings in the skirt side seams. The front edges of the skirts are pinked and scalloped. A robing of parallel padded rows of pinked silk, runs down the robings, increading in width, with applied rosettes of silk.

The petticoat is made of 5 widths of silk and part lined with green figures silk. There is a box pleat at the centre front and flat pleats at the side and back. The waist is bound with white linen tape, which forms the fastenings at the centre back. The pocket openings are hemmed to form casings for narrow linen tape drawstrings. Above the hem is a line of the padded ruching with rosettes; a deep flounce of pinked and scalloped silk is applied above it.

The ensemble was altered in the late 19th century for fancy dress. The lining of the bodice was cut away to alter the pleats at the back for a larger wearer. The pleat under the robings was unpicked; the waist seam was altered and horizontal tucks taken in the front robings at the waist. The train at the back of the sack was shortened. The waistband on either side of the back opening of the petticoat was converted to a drawstring for the linen tapes.

A cotton lining was added to the bodice, probably for museum display.
