Graceful Portrait in a Black Embroidered Dress

Ultra-detailed, refined portrait of a woman seated gracefully in a black embroidered dress. The dress features intricate gold and silver thread embroidery along the bodice and sleeves, catching soft studio light. She sits on a vintage velvet chair, three-quarter pose, hands folded in her lap, shoulders relaxed, chin slightly tilted. Her expression is serene and poised, with a subtle, confident smile. Background is a muted charcoal-gray with a hint of velvet texture. Lighting is soft, diffuse, with gentle Rembrandt-style shadows sculpting her features. Textures should be hyper-real: satin-like dress fabric, delicate embroidery, smooth skin, and fine strands of hair. Color palette: deep black dress, warm skin tones, metallic embroidery accents, subtle background tones. Overall mood: timeless elegance and grace in a modern photorealistic style.
