The image depicts a portrait of a woman from the torso up within an oval frame. She is facing slightly to her right, with delicate facial features, a high forehead, arched eyebrows, and a composed expression. Her hairstyle is an elaborate updo with a decorative element. She wears a Renaissance-style dress with a lace ruff, puffed sleeves, and intricate embroidery. Adornments include a pearl necklace and a brooch with a cross. She holds an object in her right hand, resting on her lap. The background features a herringbone pattern, with an inscription reading "Catherine de Bourbon" and decorative scrollwork including the artist's signature.
