Generate Tailor Atelier Fitting Portraits

Reference contract: Use the uploaded image as the identity anchor for the subject. Preserve the subject's recognizable likeness, face shape, eye spacing, nose shape, lip shape, skin tone and undertone, hairline, age cues, body proportions, natural expression, and gaze. Change only the wardrobe, pose, setting, lighting, and styling. Create a photorealistic portrait of the subject during a final fitting in a high-end tailor’s atelier, 4:5 vertical aspect ratio. The subject stands full-body on a low fitting platform, facing camera, wearing a nearly finished custom jacket with visible basting stitches, fine wool texture, pinned cuffs, tailored trousers, and clean shoes. Around them are fabric rolls, pattern paper, a standing mirror, a wooden worktable, measuring tape, and small pin cushions, all arranged naturally. Composition: full-body visible, feet included, camera at chest height, subject centered on the fitting platform with atelier depth behind them. Lighting: soft daylight through tall atelier windows mixed with warm practical lamps, creating realistic catchlights, gentle fabric shadows, and a calm premium atmosphere. Camera and optics: Sony A7R V, 35mm f/1.4 Sigma Art, f/2.8 aperture, 1/250s shutter speed, ISO 200. The subject must look physically present in the atelier, with matched scale, contact shadows at the feet, natural garment drape, realistic seam tension, and consistent face, neck, hand, and clothing lighting. The mirror may show partial room reflections, but not a duplicated face. Text: no in-image text. Constraints: no watermark, no visible brand logos, no extra readable labels, no duplicated reflection, no pasted-on face, no cutout edges, no mismatched face and neck lighting, no warped anatomy, natural hands, no plastic skin, no floating body effect.
