Tucked-in shirt

A medium shot, eye-level view features a solo mature female with a curvy hourglass figure and slim waist, positioned centrally against a clean white background. She has long, voluminous, flowing light blue wavy hair with individually detailed strands and colored hair lineart, framing her face. Her soft blue-grey eyes are large, highly detailed, glossy, with sharp highlights and a half-lidded, aloof expression. A beauty mark sits beneath her left eye. She wears a fitted white t-shirt with an ID lanyard around her neck and a black pencil skirt. Her right hand rests confidently on her hip, while her left arm hangs naturally by her side. Her glossy, dewy skin shows a soft blush. The background is stark white, accented by decorative blue lines and an ornate decorative corner frame. Dramatic high-contrast lighting casts deep blacks and illuminates her with a blue rim light, creating an ethereal glow. The color palette is cold and monochromatic, utilizing electric blue, silver, and white tones to establish a dark gothic atmosphere despite the white backdrop. Subtle film grain adds texture to this premium anime illustration, rendered in a semi-realistic style with smooth airbrushed gradient shading and clean medium lineart.
