Gallery of Fashion, December 1800.
The waistline here is shown much lower than in prints from other publications for this year. Even prints from this publication from five years earlier (as here) show a much higher waistline, so this dress is something of an anomaly.
The diamonds in the hair ornaments and the jewelry are picked out in bright silver metallic paint, which is unfortunately impossible to see online, but is quite beautiful in person.
The print is described in the magazine as follows:
“The front and side hair slightly frizzed; the whole of the hind hair twisted round the back of the head in a double chignon, and fastened with a diamond comb; diadême ornamented with diamonds in the front, and a diamond aigrette on the right. Robe of white satin, the bottom embroidered in gold; short sleeves: the whole trimmed with fur, and ornamented at the top and bottom of the sleeves with diamond loops. Diamond necklace and earrings. White gloves and shoes.”
