Create a fashion-forward image of a woman gracefully walking. She is wearing a light blue, classic coat and elegant black high heels with red soles. In her hand, she carries a small, dark purse. The background should be a minimalist, dark backdrop to emphasize the subject's silhouette and attire. The lighting is soft and subtle, with a focus on highlighting the textures of the fabrics and the sleekness of the heels. Use a slight grain effect to enhance the vintage, film-like aesthetic. Capture the essence of luxury and sophistication.
