The robe à la française or sack-back open robe was the most popular and lasting dress style for the fashionable women in the 18th century. So named for its association with the French court at Versailles and for the loose double box pleat of drapery that falls down the back from the shoulders. The gown is slipped on like a coat and is open at the front to reveal a matching petticoat and a triangular shaped bodice piece (which covers the corset) called the stomacher. Stomachers were usually pinned or tied in place and could be in a different fabric or match the rest of the open-robe like this one.
For much of the 18th century women's fashionable dress featured an exaggerated wide-hipped silhouette which displayed the beautiful and costly silk fabrics to full advantage. This dress features a cream silk fabric which has been brocaded in silver thread with a design of bows, ribbons and flowers. Enhancing its sumptuous appearance is an applied border of metallic bobbin lace. It was probably worn for grand occasions like attendance at court. Although the basic construction of the sack gown remained relatively unchanged, the design of fabrics changed yearly.
The exaggerated shape was achieved by layers of foundation garments including linen stays stiffened with whalebone and a hoop shaped with insertions of cane or whalebone to create a pannier effect at the sides of the garment. At a time when baths were not a daily occurrence layers of washable linen kept the costly silks away from the skin. Accessories were an important part of the total look and would include a fan, high-heeled shoes and a powdered wig.
The sack-back robe was in origin a more informal negligee gown but by the mid 1700s was worn at court and formal occasions. While women's dress changed dramatically in style in the last quarter of the 18th century these lavish panniered dresses continued to be worn as formal court dress into the early 19th century. The provenance accompanying this dress suggested it may have been worn by Lady Collingwood.
The maker of this open robe is unknown and was made in England, c, 1760
