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. Her face is softly obscured and de-emphasized, 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.
