Elegant woman in a pastel Renaissance-style gown

Photorealistic medium close-up portrait of a blousey young woman with pale platinum blonde hair swept back and flowing as if in motion, eyes closed and head tilted gracefully backward; wearing an 18th-century rococo off-shoulder silk ballgown in iridescent pastel pinks, mint and gold with lace trim, embroidered skirt panels and a tightly laced corset; warm golden rim light from left/back creates halo highlights in her hair while cool teal fill light from right adds contrast; ornate blurred baroque interior background with chandelier bokeh, shallow depth of field, eye-level camera, cinematic soft-focus. with a few enhancements in Photoshop
