Generate an image of a young woman with dark hair styled in two braided pigtails, wearing a sleeveless black outfit. She carries a large black bag over her shoulder and has a cozy black sweater draped around her arms. Her expression is calm and slightly introspective, as she stands against a soft, neutral-colored background. The lighting is warm, adding a relaxed, casual atmosphere to the image. Her accessories are minimal, including a simple necklace, completing the chic and understated look.
