Mujer elegante con vestido de satén rojo en escaleras metálicas oscuras

A woman with long wavy dark brown hair, radiant smile glancing over shoulder, light skin, subtle makeup. Wearing shiny sleeveless fire-engine red satin gown: thin spaghetti straps, extreme deep plunging V-neckline exposing cleavage, floor-length with high side slit, body-hugging fit. Standing sideways on dark metallic stairs at glamorous night event, warm red/orange lighting from below, black background with subtle glows.
