Nano Banana prompt: A realistic portrait of 17 y young female

A realistic portrait of 17 y young female, sitting gracefully on the edge of a vintage bed in a warmly lit SF bedroom. She has a very slim body with long legs, beautiful sharp abs and slightly visible veins that reflect her natural sporty body. She is wearing an elegant short-length white lace dress with subtle detailing, accessorized with gold hoop earrings and a delicate necklace. Her expression is warm and smiling, radiating confidence and dignity. The room is softly lit with a modern lamp, creating a cozy, warm, and SF atmosphere. The focus is on elegance, realism, and body positivity.
