A woman's gown of blue silk and a petticoat of cream silk twill, both embroidered to shape and with all-over sprigs, in silver thread, spangles and pastes, in a scrolling pattern of intertwined floral trails. The gown is open at the front, with a high waist and short, fitted sleeves of cream silk, ending above the elbow. The bodice and skirt are cut separately and seamed at the waist. The bodice is lined with white silk taffeta. The skirt is made of 5 widths of silk, with an inverted box pleats at each side, and 4 'nested' inverted pleats at the centre back. The skirt fronts and hem are faced with a deep band of white silk taffeta. The edges of the skirt fronts curve at the hem and are embroidered to shape. A narrow band of embroidery edges the bodice fronts. Five silver passementerie tassels and a silver-thread cord decorate the centre back of the bodice.

The skirt is made of 4 widths of silk, embroidered to shape at the hem. The hem is faced with white silk taffeta.

The ensemble was probably made as a sack and petticoat in the 1770s and remade in the late 1790s into an evening ensemble. The gown bodice fronts and back are pieced to preserve the embroidery. The waist binding of the cream silk twill petticoat was unpicked and pieced at the back to lengthen it. The gown sleeves may have been cut from the petticoat. A short bodice of pieced linen was sewn to the top of the petticoat. Another piece of white silk with the same embroidery in silver, was sewn to the front, to fill in the gown when worn. The petticoat is larger than the gown; the ensemble was possbily remade to wear over a high hoop as court dress.
