一位20岁出头的年轻女性，拥有柔和的浅棕色直长发，以自然中分披散在肩头。她随意地坐在一张现代风格的床上，身体重心微微偏向一侧臀部，双腿一屈一伸，呈现出不对称的、未加摆拍的放松姿态。她身穿一套深灰色带暗绿调的蕾丝内衣（蕾丝文胸与配套底裤），面料在光线下有柔和的织物光泽。她的面容宁静内省，眼帘低垂望向膝部，嘴唇微张放松，仅化有极淡的自然妆容，眉毛柔和，肤色均匀。她的身材苗条，骨骼纤细，腰部自然有型，胸部呈柔软的天然形状。皮肤白皙带冷调，在从窗户射入的柔和侧向自然光下，呈现出真实的肌肤纹理、细微的毛孔与自然的光影过渡，手臂、腿部、肩膀和腹部皮肤可见。摄影采用智能手机生活摄影风格，中等全身景别，竖幅9:16画幅，略带俯角。画面具有自然的锐度与细微的数字颗粒感，景深适中，背景（包括浅绿色墙壁、木质床架、白色床品、米色针织毯和简约电视柜）略微虚化但仍可辨识。整体氛围是午后室内的静谧与私密感，构图略带不完美，传达出一种真实、未加脚本的社交媒体现实主义美学。必须保留：自然日光、随意的不对称感、真实的皮肤纹理、极简妆容、室内卧室环境。避免：影室灯光、重度修图、过度戏剧化的姿势、夸张的身体比例、过曝的高光。
A young woman in her early 20s with soft, cool light brown straight hair, naturally parted in the middle and falling along her shoulders. She sits casually on a modern bed, weight shifted slightly to one hip, legs asymmetrically positioned with one bent and one extended, embodying an unposed, relaxed posture. She wears a deep gray lace bralette and matching bottoms with a muted green undertone, the fabric showing a subtle sheen under light. Her expression is introspective and serene; eyes gently lowered toward her lap, mouth slightly parted and relaxed, featuring minimal natural makeup with soft brows and even skin tone. She has a slim, delicate frame with a naturally defined waist and soft natural chest shape. Her skin is fair with cool undertones, displaying realistic texture, subtle pores, and natural variations, illuminated by gentle side daylight from a window that creates smooth shadow transitions and mild highlights on her arms, legs, shoulders, and midriff. Photography style is smartphone lifestyle, medium full-body shot in vertical 9:16 aspect ratio, from a slight high angle. The image has natural sharpness with subtle digital grain, moderate depth of field where the background (muted light green wall, wooden bed frame, white bedding, beige knitted blanket, minimal TV stand) is slightly softened but readable. The overall vibe is an intimate, quiet afternoon pause, featuring authentic social media realism with slightly imperfect composition and natural posture. Must keep: natural daylight, casual asymmetry, realistic skin texture, minimal makeup, indoor bedroom context. Avoid: studio lighting, heavy retouching, overly dramatic posing, exaggerated body proportions, overexposed highlights.
