Sack back

The sack-back gown was the most popular style of formal dress for women in the mid-18th century. It was loose at the back, with the fabric gathered into pleats at the shoulder. In front, the gown was open, showing off a decorative stomacher and petticoat. This example is decorated with ruchings and ruffles of the same silk, edged with white fly fringe (a type of silk fringe). The arrangement of these decorations in curves and loops shows Rococo influence. The bright yellow colour of the silk was a popular shade in 18th century women’s dress.
