A highly realistic female model wearing a black satin slip dress with delicate lace trim, walking slowly through a dimly lit bedroom at night. Cinematic lighting with soft shadows and subtle highlights accentuates the silk fabric’s natural sheen and flow. The dress moves gently with each step, draping smoothly along the body. The model’s movements are calm and restrained, with natural posture, subtle breathing, and realistic body proportions. Shallow depth of field, film-like color grading, intimate and elegant mood. Ultra-realistic texture, accurate anatomy, no distortion, no extra limbs. Luxury nightwear commercial aesthetic. Vertical 9:16 format, smooth camera motion, 8–10 seconds.
