anime illustration, An anime illustration of an original schoolgirl with straight black hair, wearing an elaborate summer Milky Way-themed yukata in deep navy blue. The yukata features dramatically oversized round sleeves adorned densely with silver-white star particles, lightning-blue flow lines, faint purple nebula patterns, white dot accents, and fine gold orbit lines. The body is deep navy with intricate weave texture, finished with delicate silver piping on the overlapping front edges, a pure white collar, and a sheer pale aqua inner layer. The sleeve cuffs are double-layered, combining translucent aqua organza above the outer navy fabric, with several small star-shaped charms dangling from the hem. Her obi is a layered construction, featuring a wrinkled silver-white heko obi beneath two floating, transparent PVC ring belts studded with small star acrylics, silver beads, pale blue spheres, and short chains. At the center, her obi is secured by a thick navy cord and a large crescent-moon metal belt buckle. The back features a large two-tiered bow with silver borders and trailing aqua gradient drapes. The hem shows heavenly galaxy motifs along the back, contrasted by the solid navy front, with scattered star-embroidery at the edges. She wears white tabi socks and traditional black wooden geta sandals with aqua straps and silver stars on the sides. The whole illustration is detailed with a full body, high-resolution anime styling, featuring clean lines and vibrant colors against a plain white background.
