Portrait after a Costume Ball (Portrait of Madame Dietz-Monnin)

Degas employed soft, feathery brushstrokes to render the subject's attire, imbuing the image with a sense of lightness and delicacy, while the blurred background subtly recedes from the central figure.

Created in 1889, the work is now held in the permanent collection of the Art Institute of Chicago, though specific details of its provenance prior to acquisition are not provided here.

This piece aligns with Degas' propensity for capturing women in everyday, introspective moments, characteristic of his broader oeuvre focusing on modern life.
