Envision a set of ethereal ballerina nails, taking inspiration from the grace and elegance of a prima ballerina on stage. The base should be a sleek, soft pink, reminiscent of satin pointe shoes, while intricate white lace patterns gracefully adorn each nail, mirroring the delicate tutus of classical ballet. Add a touch of shimmer to a select few nails, like the sparkle of stage lights, enhancing the overall allure and sophistication. Finally, incorporate subtle crystals or gems to mimic the delicate embellishments on a ballerina's costume, completing the dance of elegance on your fingertips.
