The image shows a woman in a side profile portrait. She is seated and facing right, with her head slightly tilted downwards. She has delicate and well-defined facial features with a soft expression. Her hair is styled elegantly, gathered at the top with decorative detailing, possibly a cap or net with lace trim. She is wearing a garment with ruffled detailing along the neckline and sleeves, indicative of 18th-century fashion, and a small round earring is visible. The background features an oval frame with a patterned interior, with a classic sepia tone. The portrait is set on a plain background with text below the image reading "Mrs. Montagu."
