An anime-style illustration of a beautiful girl, shown from below the eyes down. She is wearing only an oversized white dress shirt, giving a casual and slightly whimsical feel. The shirt should be noticeably large, emphasizing a cozy and relaxed vibe. The setting is indoors, with soft morning sunlight streaming through a window, creating a warm and gentle atmosphere. A subtle bokeh effect adds depth and softness to the scene. The image should be high resolution and high definition, capturing the delicate details of the girl's features, the texture of the shirt, and the serene ambiance of the room. The overall composition should be a masterpiece, blending a cozy and tranquil mood with a touch of elegance.

Avoid any clutter or distracting elements in the background. Do not include overly exaggerated facial expressions, cartoonish features, or unrealistic proportions. Exclude any harsh lighting or shadows that detract from the soft morning light and serene atmosphere. Avoid using dull or muted colors; ensure the colors are vibrant and true to the scene's warm ambiance. Do not include any other characters, overly complex patterns, or textures that could divert focus from the main subject. Exclude any elements that could imply a lack of elegance or refinement in the composition.
