Highly realistic full-body portrait of a young Portuguese woman scientist from the 1930s, age 27, standing confidently. She has light olive skin, brown expressive eyes, and a soft but determined expression. Her dark chestnut hair is styled in a low bun with a side part. She wears a well-fitted, navy-blue, long-sleeved mid-length wool dress with small buttons, a thin belt, and a small collar. Her footwear consists of polished brown leather Oxford shoes. She holds a rolled-up scientific paper or journal in her hands. The background is neutral or softly blurred to keep the focus on her figure. Natural lighting enhances the textures of her skin, clothes, and hair, giving a photo-realistic quality.
