IDENTITY PRESERVATION INSTRUCTION: Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming the overall appearance to match the preppy aesthetic.

TRANSFORMATION DESCRIPTION: Transform the subject into a sophisticated preppy style with classic collegiate fashion elements. Dress the person in timeless preppy wardrobe staples such as a well-fitted polo shirt, Oxford button-down, cable-knit sweater, or blazer with crisp chinos or khaki trousers. Include classic accessories like a leather belt, watch, pearl necklace, or silk scarf. The grooming should be neat and polished - clean hair style, well-maintained appearance. The overall look should evoke an upscale academic, country club, or Ivy League atmosphere.

- Classic preppy color palette: navy blue, burgundy, forest green, cream, white, camel, and subtle pastels
- Clean, crisp fabric textures visible (cotton, wool, leather)
- Natural to soft lighting that highlights the outfit details and facial features
- Background should be upscale and appropriate: library, campus grounds, country club, garden, or clean neutral background
- Hair should be neatly styled (clean cut, blowout, or classic updo)
- Makeup should be natural and polished (if applicable)

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and outfit details
- Professional portrait photography quality
- Natural skin texture preserved
- Cinematic or editorial photography style
- Aspect ratio: 1:1 or 4:3 for portrait (adjust as needed)
