Mlle. Marguerite Catherine Haynault, later the Marquise de Montmelas in Turkish Costume

Executed in oil paint, the portrait showcases Drouais's rococo style. A dark background focuses attention on the subject's face and attire, highlighting the intricate details of her costume and jewelry.

Created in 1757 for the French nobility or wealthy Parisian society, the painting was later acquired by the Museum of Fine Arts, Boston, where it remains part of the permanent collection.

The painting reflects 18th-century European fascination with Turkish culture, as well as contemporary fashion trends that incorporated exotic elements. Drouais's work catered to the royal family, nobility, and high society, contributing to his popularity at court.

As a characteristic example of Drouais's portraiture, the painting illustrates the artistic preferences of the French elite during the late Louis XV period, preserving a glimpse of the era's social and aesthetic values.
