In Seated Lady in Black, Trouville, a woman is depicted seated in a relaxed pose. She wears a black dress that contrasts with the lighter background. The colors are soft, with gentle brush strokes that create a sense of movement.

The setting suggests a casual atmosphere, typical of Boudin's work during this period. The painting is executed in oil on canvas, showcasing Boudin's characteristic Impressionist style. The brushwork is loose and fluid, allowing for a sense of immediacy. The dimensions are approximately 65 x 81 cm, making it a medium-sized portrait.

The use of light and shadow adds depth to the figure and the surrounding space. Eugène Boudin was a pioneer of Impressionism, often focusing on scenes of leisure and everyday life. This work reflects his interest in capturing the essence of modern life in 19th-century France. An interesting fact about this painting is that it showcases Boudin's ability to portray the subtleties of fabric and texture, particularly in the black dress of the lady.

Boudin was known for his outdoor scenes, but this intimate portrait highlights his versatility as an artist.
