Camera is slightly above eye level, framing from upper chest to top of head, with a subtle tilt. The woman has long, softly waved medium-brown hair with natural highlights, parted slightly off-center.\n\nStyling details (must match): {argument name=\"sunglasses type\" default=\"tortoiseshell cat-eye sunglasses\"} with dark lenses; soft glam makeup with natural brows, subtle contour, and full glossy rose-nude lips; a chunky gold hoop earring visible; layered pearl necklaces including a statement pendant charm. Outfit: light blue thin-striped button-up shirt, collar open, slightly oversized fit.\n\nEnvironment: bright modern interior with a white wall/tiles on one side, a wooden louvered door or panel behind, and a white cabinet/ceiling fixture in the background. Background should be softly out of focus (shallow depth of field).\n\nLighting: natural window light, soft and even, with realistic reflections visible on the sunglasses lenses. Preserve real skin texture and pores; avoid smoothing or beauty retouching. No text, no logos,"
