Couture gown swirls in teal and violet smoke on runway

Photorealistic haute couture runway-style editorial photograph, full-body shot, shot on 85mm f/2.8 lens, dramatic studio lighting against a deep midnight-navy black backdrop, colored smoke effects in teal, cobalt blue and violet swirling behind her, soft beauty-dish key light with cool blue and purple rim lights, vertical 9:16 composition, looks like a real high-fashion magazine shoot for Vogue or Harper's Bazaar.

A tall, elegant young woman with very long, voluminous, wavy dark hair with deep violet and plum tones, windswept and flowing past her shoulders. Fair luminous skin with visible pores and natural texture, soft pink blush, light teal-green eyes, soft rosy lips, a calm, graceful, slightly mysterious expression, looking at the camera with her head slightly tilted. Delicate crystal drop earrings in blue and violet.

She wears a spectacular couture gown with a strapless sweetheart bodice embroidered with hand-sewn beads, sequins and tiny crystals in teal, sapphire and amethyst, forming a floral, vine-like pattern over sheer nude tulle. The skirt is made of dozens of layers of sheer silk organza and tulle in teal, aqua, deep indigo and purple, with voluminous ruffles, high thigh-length slit, and a long flowing train billowing as if caught in motion. The translucent layers overlap to create rich color blending, with realistic fabric transparency, sheen and soft folds.

She wears black strappy ankle-strap high-heel sandals with small crystal embellishments. Her pose is elegant and dynamic: one leg crossed forward, one arm relaxed at her side, her body slightly turned, full body visible from hair to shoes, standing on a glossy dark reflective studio floor.

Color palette: teal, aqua, cobalt blue, indigo, violet, deep navy-black, soft skin tones. Realistic fabric and bead texture, dramatic contrast, shallow depth of field on the background smoke, sharp focus on the subject, subtle film grain, ultra-detailed, 8K. Clean image, no text, no watermark.
