Create a realistic and highly detailed full-body image of a character with these features: a mystical and celestial-themed woman with a serene and graceful aura. She has silver-white hair styled with a large, ornate accessory that resembles a moon. Her attire is a flowing robe with a long sash, decorated with gold accents and moon motifs. The robe should have delicate floral patterns and ethereal, trailing elements that suggest a connection to the sky and the moon. Her expression is calm and composed, with a touch of otherworldly elegance. The background should have a celestial theme, with soft moonlight and clouds, to enhance the character's divine and lunar connection.
