Ethereal Blue Fantasy Fashion Portrait

Create a vertical fantasy fashion portrait of {argument name="character name" default="an ethereal young woman"} standing in a dark midnight-blue void, shown from about mid-thigh upward in a graceful three-quarter pose. She has long windblown {argument name="hair color" default="black hair with electric-blue highlights"}, a softly obscured, dreamlike face with no sharp facial detail, pale luminous skin, one hand resting near her collarbone and the other relaxed downward. Dress her in a dramatic {argument name="dress color" default="deep cobalt blue"} couture gown made of sheer flowing chiffon, glossy wet-look fabric, sequins, beadwork, lace appliqué, and floral embroidery, with an off-shoulder asymmetric neckline, delicate shoulder straps, translucent sleeves, side cutouts, and long ribbons of fabric swirling around her body. Surround her with explosive liquid-like blue smoke, ink clouds, splashing water, glowing particles, and bioluminescent blue flowers in the foreground and background. Use a monochromatic palette of navy, ultramarine, cobalt, and electric cyan, with intense rim lighting behind the figure, sparkling highlights on the dress, high contrast shadows, soft bokeh blossoms near the bottom, and a magical underwater-night atmosphere. Style: ultra-detailed cinematic digital art mixed with high-fashion editorial photography, elegant, romantic, mysterious, sharp fabric texture, volumetric light, dynamic motion, no text, no watermark.
