Create a 9:16 vertical 3D CG fantasy illustration of an adult East Asian celestial woman in a dreamy galaxy-fairy style. Place her slightly left of center from upper body to mid-thigh, with a natural elegant S-curve pose, softly tilted shoulders, a gentle waist twist, and a calm three-quarter face. Give her translucent pale skin, delicate features, long eyelashes, and long silver-white hair fading into pale pink lavender, flowing to the right like windblown starlight. Dress her in an elegant galaxy gown made of light tulle and translucent silk, with pastel pink, pale blue, lavender, pearl white, gold stardust accents, and spiral nebula ribbons around her body. Set the background in a soft cosmic dream space full of fine stars, dust particles, galaxy streams, holographic light ribbons, pastel mist, and warm rim light from the upper left. Keep the image elegant, high-end, romantic, ethereal, softly glowing, richly detailed, and free of readable text, logos, or watermarks.
