A woman's sack and petticoat of yellow ribbed silk, painted in floral sprigs with coloured pigments. The sack is open at the front with robings to the waist and elbow-length sleeves with double, scalloped and pinked sleeve ruffles. The bodice and sleeves are lined with linen. There are two, double box pleats at the back stitched at the neck line. The sack is made of 3 widths of silk, with a partial panel and triangular gore on each side of the front. The hem of the skirts is partially faced with white silk taffeta. The front edges are pinked and scalloped. A narrow pinked ruching of silk, arranged in a serpentine line, decorates the skirt fronts. The ruching is also on the robings.

The petticoat is made of 6 widths of silk. Both centre back and centre front have a box pleats with flat pleats on either side. The waist is bound with a narrow strip of yellow silk ribbon with a picot edge. This ribbon forms the fastening on the right side. A deep flounce of silk decorates the petticoat front. Narrow bands of ruching, arranged in overlapping zig-zags, are stitched above.

The waist was altered sometime during the 1760s or 1770s. The skirts were originally pleated evenly across the front. These were unpicked and rearranged at the pocket openings, and the skirt fronts resewn flat to the bodice.
