Casual portrait of young woman in sailor blouse at city cafe AI Image Prompt

A candid smartphone-style portrait photo of a {argument name="subject" default="young woman"} sitting at an outdoor cafe in a modern city business district, framed from the chest up in a vertical composition. She has {argument name="hair color" default="dark brown"} hair tied back in a low ponytail with soft side bangs and a natural, understated everyday look. Her outfit is a Japanese-inspired sailor-style blouse in white with navy trim, short puff sleeves, a wide sailor collar, and 1 large navy bow at the center of the chest, paired with a navy garment visible at the waist. She wears 1 delicate necklace with a small heart-shaped pendant and 1 beige crossbody bag strap running diagonally across her torso. Her arms are relaxed in front of her, and in the lower right foreground there is 1 takeaway coffee cup with a kraft paper sleeve and black plastic lid, slightly close to the camera. The setting includes glass building facades, tall office towers, pavement stones, and a bright overcast daytime atmosphere, with a shallow depth of field that keeps the background softly blurred. The image should feel ordinary, casual, and realistic, like a spontaneous everyday photo, with soft natural light, neutral colors, subtle skin tones, and a clean urban lifestyle aesthetic.
