In Dame met pluimhoed en Achterzijde van dame met handtas, we see a lady adorned with a feathered hat. The colors are rich and vibrant, with a focus on the intricate details of her attire. The background is softly blurred, drawing attention to the figure in the foreground.

The overall composition exudes elegance and sophistication. The painting employs oil on canvas, a medium that allows for smooth blending of colors and fine details. The brushwork is delicate, particularly in the rendering of the feathers and fabric textures. The dimensions are approximately 60 x 80 cm, making it a substantial piece that commands attention.

The use of light and shadow enhances the three-dimensionality of the figure. Alfred Ost was known for his portraits that often featured fashionable women of his time. This particular work, created around 1900, reflects the Art Nouveau style, characterized by its decorative elements and flowing lines. An interesting fact about this painting is its emphasis on the hat, which was a significant fashion statement in the early 20th century.

Ost's ability to capture the essence of elegance in his subjects is evident in this piece.
