A woman stands full-length against a dark, shadowy background, her body turned slightly to the right while her face looks out toward the viewer. She wears a voluminous black gown with a subtle patterned texture, its surface catching the light in ripples and folds, and the fabric is trimmed with elaborate white lace at the collar and cuffs. Her right hand, adorned with a gold ring and a delicate bracelet, rests gently on her hip, while her left hand holds a black feather fan suspended from a long gold chain.

A wide, pale sash with a large decorative bow encircles her waist, and a string of pearls frames her face and drapes across her hair, which is parted in the center and softly curled. The light falls from the left, illuminating her face, the intricate lace, and the gold jewelry, while her black dress and the background remain in deep shadow, creating a dramatic contrast. Her expression is calm and composed, with a slight, poised smile and a direct, steady gaze.

The floor beneath her is paved with large, pale tiles, and the lower edge of her dress reveals a glimpse of an embroidered white shoe. The composition is vertical and monumental, emphasizing her stature and the luxurious details of her attire, while the plain background focuses attention entirely on her figure. Paint is applied with precision, especially in the rendering of the lace and jewelry, where fine brushwork captures the textures and reflections of each material. Portrait of Oopjen Coppit was created by Rembrandt in 1634 in Amsterdam.
