create one original supporting-performer costume design for a photorealistic psychological fashion music video, a single fully headed adult human performer in a clear full-length standing character-master portrait. vertical3:4 composition, complete topmost head/collar structure to both boot soles, spacious enough to read the whole silhouette, natural adult proportions and real human hands. the user selected a hybrid design: a real human body with a specifically designed abstract head or sculptural clothing construction. this is a wearable constructed stage costume, with believable joints, closures, fabric weight and physical materials, not a generic black helmet suit. the attached image is the existing heroine-and-set context only, not an identity to copy: the heroine wears brilliant ivory and chrome mirrored back fins in a charcoal/champagne tilted-mirror chamber. this new design is one of her subordinate attendants, so it must use lower-brightness matte graphite, ash or smoked metal and must not copy her visible face, ivory fin crown, long bridal train or exact costume. the attendant is an original gender-neutral-looking adult with a distinct supporting silhouette; facial identity is intentionally obscured by the actual costume construction. photo-realistic couture fabrication, seams, weave, controlled reflections, matte human hand texture where visible. neutral dark-gray studio backdrop, readable soft neutral frontal light and a restrained warm edge that echoes the set. one person only, no heroine in the same image, no collage, labels, text or logo. clearly designed head silhouette, torso construction, sleeves, lower garment and footwear should all be readable. human anatomy stays normal under the costume, the head structure is wearable, not a severed head or a biological mutation. specific design: a — mirror-faced attendant. the entire face is covered by one elongated vertically oriented smoked-silver mirror plate, roughly one-and-a-half normal face heights, with a sharply slanted hexagonal outline and a fine dark gunmetal perimeter. it extends a little above the normal crown but is visibly a thin wearable object rather than an inflated robot head. a real normal neck and high collar below it clarify the human body. the mirror catches one abstract warm strip of the stage light and a faint ivory reflection, never a painted human face, eye openings or the heroine's duplicated face. narrow tailored graphite felt long coat with a high slit collar, slightly squared but restrained shoulders, sharp vertical panel seams, a wrapped asymmetrical front and a stiff compressed pleated insert down one side. long slim sleeves end in fitted matte-black gloves; the hands rest naturally apart at the lower abdomen. straight narrow charcoal trousers and black boots with a low architectural heel. a little metal articulation at the collar allows the head plate to turn and bow with the person; keep this secondary and believable. the overall design is a sophisticated
