Starlit Dream Girl

A full-body anime illustration depicting a dreamy celestial girl floating diagonally against a pure white background, as if weightless in open air, viewed from above. She has extremely long flowing {argument name="hair color" default="deep navy blue"} hair, gracefully swirling around her body like elegant ribbons, with glossy highlights, scattered loose strands, and a star-shaped hair ornament on one side of her head. Her face is softly blurred, with the composition emphasizing her delicate pose, detailed clothing, and surrounding magical atmosphere. She wears a richly detailed white-and-blue sailor-inspired fantasy dress featuring translucent layered sleeves, ruffled lace, shimmering lace details, lightweight sheer fabrics, and a huge star-shaped crystal brooch on the chest. The outfit contains 5 clearly visible elements: a short ruffled dress, a sailor collar and neck ribbon, translucent detached sleeves or draped chiffon layers, one leg wearing a white thigh-high stocking, and the other leg wearing a deep-blue starry-pattern thigh-high stocking with a matching garter. She is barefoot, with both feet clearly visible. Her pose is elegant and flowing: one arm stretches upward with the palm open, the other hand rests against her chest, one leg is extended straight while the other is slightly bent. Surround her with glowing cool-blue constellation motifs, including 6 prominent five-pointed star decorations scattered around her, countless tiny sparkling stars, circular watercolor-style swirls, floating bubbles, and ornate crescent-shaped circular filigree rings partially framing the composition. Use a palette of ice blue, cobalt blue, indigo, and white, accented with shimmering sequin-like textures, soft translucent overlays, crisp line art, and a light ethereal glow. The overall atmosphere should feel magical, elegant, airy, and tranquil, like a celestial girl floating beneath a winter night sky, presented on a pristine white canvas.
