Rokumeikan Ballroom Portrait

A cinematic, photorealistic portrait of a [ethnicity] woman dancing at an opulent Rokumeikan-era ballroom reception in late 19th-century Japan, shown from about the waist up in a three-quarter pose and turning slightly to her left. She wears an elegant [dress color] Victorian-inspired evening gown with a tightly fitted corseted bodice, soft sheen satin fabric, layered lace ruffles along the neckline and shoulders, decorative buttons and floral trim on the front, and long matching opera gloves. Her hair is dark and styled in a refined formal updo with curled sections and a delicate jeweled hair ornament, and she wears drop earrings plus layered necklaces with a small pendant. She holds a folded fan or small clutch in one gloved hand near her waist. The setting is a grand historic ballroom with warm amber gaslight or chandelier lighting, shallow depth of field, and a softly blurred crowd of exactly 4 visible background guests in formal attire: 2 women and 2 men. Behind her are dark-suited gentlemen, women in period dresses, and a large floral arrangement, all rendered as elegant bokeh shapes. The mood is romantic, nostalgic, and luxurious, with rich sepia-gold tones, soft cinematic contrast, realistic skin and fabric textures, and the feeling of a graceful dance at [venue style]. Compose it like a high-end historical film still, vertical portrait framing, centered heroine, natural posture, poised and aristocratic.
