Realistic Teacher in Math Classroom

Adjust the frame to a vertical 9:16 aspect ratio. Maintain the exact clothing style, color, fabric texture, stitching, and layering details of the light-blue denim cross-strap vest and off-white layered skirt from the reference image without changing the core design. The image should have a realistic, natural, high-definition, and soft photographic texture, featuring a young woman around age, approximately height tall, with cool fair skin and long brown curly hair, wearing the same outfit and transparent heeled sandals. Remove all handheld items and bags. She wears a red work badge around her neck and is lifting her hand to explain, with a natural expression looking toward the front. The figure is complete and prominent. The background is a fresh and trendy classroom, with a black chalkboard on the left filled with math formulas, functions, and derivatives, and an electronic whiteboard on the right showing math problems with red annotations. A light wood lectern sits in the right corner with books and tablets. The overall tone is classroom white and chalkboard black with soft indoor light. The clothing is the focal point, creating a purchase-worthy look with no AI artifacts.
