Anastasia stands on a dedicated base shaped like a crescent moon beneath a tapestry of tiny stars. The figure wears a flowing bridal gown in midnight blue that shifts to pale silver at the hem, with a subtle gradient that catches light from different angles. Intricate star-embroidery decorates the bodice and skirt, rendered with shimmering accents that evoke constellations. Her long, dark hair is styled in graceful waves, crowned with a delicate tiara and ribbons that flutter with her pose. Her eyes carry a calm, confident gaze, and the pose—one arm extended in a soft, inviting gesture—evokes on-stage elegance. The dress features shiny materials, gem-like appliqués, and translucent layers that create a luxurious, premium look befitting the Starry Bride concept.
