  "facial_structure": "Distinctive heart-shaped face morphology with a soft yet defined mandibular angle; characteristic slightly hooded, downturned blue-grey eyes with heavy upper lids; full vermilion lips featuring a sharp Cupid's bow and natural volume; forensic-level orbital and malar bone definition.",

  "hair": {

    "style": "Voluminous honey-blonde hair styled in signature messy cinematic waves; soft curtain bangs framing the temples with high-fidelity strand separation; strands cascading naturally over the shoulders and interacting with the fabric of the dress.",

    "color": "#F2D2A9 warm honey blonde with #FAF3E0 pale platinum highlights",

    "physics": "Natural hair luster with realistic subsurface scattering on fine strands; zero synthetic clumpiness; micro-hair details visible at the hairline."

  },

  "ocular_details": "Iris pattern with intricate radial furrows in a blue-grey #7A9E9F hue; visible limbal rings; anatomically correct sclera hydration; realistic lacrimal caruncle placement.",

  "dentition": "Standard human dental alignment with natural incisor transparency; visible through a relaxed, slightly parted lip position."

},

"body": {

  "somatotype": "Ecto-mesomorphic frame with a high waist-to-hip ratio; precise anatomical muscle definition in the rectus femoris and forearms; defined clavicle and suprasternal notch visibility.",

  "skin_physics": {

    "base_tone": "#F5E1D2 creamy porcelain",

    "surface_properties": "High-fidelity subsurface scattering (SSS) on epidermal layers; visible follicular pores and micro-creases on joints; zero artificial smoothing filters; natural skin luster.",

    "details": "Natural mole and freckle distribution mapped to biometric reference; absence of digital artifacts or synthetic blurring; realistic skin compression where the body meets the bedding."

  }

}

},

"wardrobe": {

"primary_garment": {

  "type": "Form-fitting corset-style mini-dress",

  "color": "#FEEFB3 soft yellow and #FFFFFF optic white gingham pattern",

  "material_physics": "Fine-weave cotton gingham fabric with subtle texture; realistic fabric micro-creases indicating structural tension at the waist; matte ruffles at the hem with subtle translucency."

},

"neckwear": {

  "type": "Matching yellow gingham bowtie with a white detachable Peter Pan collar",

  "color": "Bowtie: #FEEFB3 and #FFFFFF; Collar: #FFFFFF optic white",

}

},

"pose_action": {

"description": "Seated centrally on plush white linen bedding; legs are angled in a dynamic side-profile tuck to emphasize femoral elongation; torso is rotated 30 degrees toward the primary light source; hands are positioned as natural anchors on the bed surface with realistic finger articulation and joint creases; head is tilted slightly with a focused cinematic gaze toward the camera.",
