Use the uploaded photo as the primary and definitive reference for the person’s face, skin, and hair.
Preserve the exact hairstyle, length, texture, direction, and color from the uploaded image — no reinterpretation, no added volume, no restyling.
Do not modify, smooth, or recolor the hair.
Facial features, proportions, and natural expression must remain identical to the reference.
🪑 Scene and Composition
A woman is sitting on a tall wooden stool with a black metal frame, in a minimalist gray studio.
Full-body vertical portrait, slightly distanced framing to highlight posture and the simplicity of the space.
Background: neutral gray with soft gradient — clean, professional, and distraction-free.
🧍♀️ Pose
Right leg bent and resting on the stool’s step.
Left leg extended with foot lightly touching the floor.
Wearing elegant black high heels.
Posture exudes confidence and sophistication.
👗 Outfit
Full black ensemble: tailored slim-fit trousers, refined blouse, and structured blazer draped over the shoulders.
Fashion-forward, elegant, and professional aesthetic.
💇♀️ Hair and Expression
✅ Hair must remain exactly as in the uploaded photo — same length, volume, texture, and direction.
No new strands, no longer or shorter length, no new styling.
Expression remains calm, confident, and composed.
Gaze directed slightly to the side.
💡 Lighting
Soft directional studio lighting for realistic depth and contrast.
Highlights emphasize natural skin texture and fabric detail.
Light position sculpts facial structure and creates cinematic realism.

High-end fashion editorial portrait with modern corporate elegance.
Ultra-realistic photographic quality with refined contrast and tonal depth.
