Luxury Idol Cosplay Portrait

Create a highly detailed vertical fashion portrait of a glamorous anime-idol inspired woman on a dark concert stage, framed from the waist up. She has {argument name="hair color" default="platinum blonde"} hair in huge high twin ponytails with soft curled ends, straight bangs, and braided side details, topped with an oversized fluffy white bow decorated with black satin stripes and gold trim. Dress her in a luxurious white cropped military-style jacket with black-and-gold striped cuffs, collar, and shoulder trim, gold rope braids, gold chains, and ornate epaulet details. Under the jacket she wears a glossy black lace-up corset crop top with white fur trim at the neckline, plus a black choker with a gold ring, layered gold necklaces, dangling gold geometric earrings, and white gloves; one gloved hand is raised near the choker while the other rests at the hip. Use dramatic backstage spotlighting with bright circular lights in the upper corners, cool blue-gray haze, strong rim light on the hair, shallow depth of field, ultra-polished cosplay photography, crisp fabric and hair texture, high contrast, elegant black white and gold color palette, rounded image corners, no visible text.
