Woman's petticoat made of pale blue silk taffeta, lined with coarse glazed pale blue wool and wadded with a thin layer of wool. It is quilted in running stitch with blue silk thread in a horizontal pattern of large flowers and leaves around the hem, with undulating lines in a diamond pattern above. The petticoat is made of 7 panels of silk with pocket openings at the side seams. There is a wide box pleat with pleats on either side at the centre front and an inverse box pleat with pleats on either side at the centre back. The hem is bound with ¾ inch (2 cm) wide blue silk ribbon and the waist with ⅞-inch (2.1 cm) wide linen tape.
The petticoat was altered in the late 19th century for fancy dress. The waist ties were cut off and replaced with a hook and eye on each side.
