Met Gala Couture Staircase Portrait

Create a full-body vertical editorial fashion photograph of {argument name="character name" default="a glamorous anime-inspired woman"} posing on the Met Gala staircase, centered and slightly turned with one hand gathering the skirt. She has {argument name="hair color" default="vivid purple"} hair styled in a high braided crown updo, elegant earrings, and a confident red-carpet posture; keep the face softly anonymized with a smooth skin-toned blur and no visible facial features. The setting is a crowded luxury gala entrance with dark-suited photographers in the background, bright camera flashes, cream-and-blue carpeted stairs with small star motifs, and dense cream flower hedges along the staircase. The outfit has exactly 6 main visible components: 1) a sculpted ivory corset bodice with sweetheart neckline, 2) a draped ivory satin skirt with long gathered train, 3) a deep midnight-navy velvet overskirt panel, 4) a long midnight-navy velvet open coat/cape with sweeping train, 5) ornate silver crystal floral embroidery and beaded appliqué cascading over the bodice, hips, sleeves, and hem, and 6) a black choker with a small pendant. Use {argument name="gown color palette" default="ivory satin, midnight navy velvet, silver crystal embellishments"}, ultra-luxury couture detailing, realistic fabric texture, cinematic flash photography, shallow depth of field, high contrast, glossy magazine quality, 3:4 vertical composition, no logos, no text, no watermark.
