Tenue d'enseignante en classe moderne

Vertical full-body fashion portrait of a [25 years old] woman, approximately [160cm] tall, with cool fair skin and long brown curly hair, standing and gesturing to explain in a classroom. She wears the exact clothing from the reference photo: a light-blue denim cross-strap vest and an off-white layered skirt, keeping every detail of the fabric texture, color, stitching, and layering unchanged. She wears a red work badge lanyard around her neck and transparent heeled sandals, with no handheld items or bags. Her expression is natural and engaging as she looks toward the camera with one hand lifted in explanation. Setting: A modern, stylish classroom with soft indoor lighting. On the left is a black chalkboard covered in handwritten mathematical formulas, functions, and derivatives. On the right is a digital whiteboard displaying math problems with red annotations. A light wood lectern with books and a tablet stands in the right corner. The color palette balances clean classroom whites and deep chalkboard blacks, highlighting the clothing textures naturally without artifacts.
