Create a mesmerizing ballerina nails design inspired by a twilight sky filled with shimmering stars. Paint the nails in a deep, rich indigo base as though reflecting the evening hues just after sunset. Add delicate, silver star decals that seem to twinkle and glisten when caught in the light. Finish off with a glossy topcoat to capture the ethereal shimmer and elegance reminiscent of a ballet performance at dusk.
