Vintage film-style candid portrait of a laughing woman in a park

A candid, film-style portrait of a joyful young woman with long, voluminous, wavy light brown hair with blonde highlights, laughing heartily with her eyes closed and mouth open in a genuine, ecstatic expression. She has a small purple flower tucked behind her ear, and her hair is slightly windswept across her face. She is leaning slightly forward toward the camera, wearing a matching lavender-colored long-sleeve top and shorts set. The background is a sun-drenched outdoor park with green grass, shaded areas, and tall pine trees under bright sunlight, captured with a vintage 35mm film aesthetic, subtle grain, warm sun flares, and a soft, desaturated color palette.
