Imagine a festive nail design inspired by a lively birthday party. Incorporate vibrant confetti patterns and balloon motifs against a pastel background to evoke a sense of celebration. Use a glossy finish to give the nails a polished look, reminiscent of a freshly baked birthday cake. Add tiny shimmering rhinestones at the base of each nail to mimic the sparkle of birthday candles. Finally, choose a playful accent nail with a gift box design to complete the celebratory theme.
