Celestial Blue Anime Girl Floating

A full-body anime illustration of a dreamy celestial girl floating diagonally across a pure white background, viewed from above as if weightless in open air. She has very long, flowing {argument name="hair color" default="deep navy blue"} hair spreading in elegant ribbons around her body, with glossy highlights, loose strands, and star-shaped hair ornaments near one side of her head. Show every face clearly with natural, detailed facial features, while the composition focuses on her delicate pose, costume, and swirling magical atmosphere. She wears a highly detailed white and blue sailor-inspired fantasy dress with translucent layered sleeves, frilled ruffles, sparkling lace, sheer fabric panels, and a large star-like crystal brooch at the chest. The outfit includes 5 clearly visible clothing elements: a short frilled dress, a sailor collar and neck ribbon, semi-transparent detached sleeves or draped chiffon layers, 1 white thigh-high stocking on one leg, and 1 dark blue starry thigh-high stocking on the other leg with a matching garter band. She is barefoot, with both feet visible. Her pose is graceful and drifting: one arm reaches upward with an open hand, the other hand rests near her chest, one leg extended and the other slightly bent. Surround her with a luminous constellation motif in cool blue tones, including exactly 6 prominent five-pointed star ornaments scattered around her, multiple tiny star sparkles, circular watercolor-like swirls, floating bubbles, and ornate crescent-ring filigree arcs framing parts of the image. Make the palette icy blue, cobalt, indigo, and white, with shimmering glitter textures, soft translucent overlays, crisp line art, and a light ethereal glow. The overall mood is magical, elegant, celestial, and serene, like a star maiden suspended in a winter night sky interpreted on a clean white canvas.
