Imagine a nail design that brings to life the relaxing and soothing feel of a bubble bath. Picture a subtle, serene shade of baby blue as the base color representing the calming water. Add delicate, glossy white elements that mimic the tranquil bubbles dancing on the surface. Introduce iridescent shimmer for a sparkling touch, reminiscent of the light reflecting off the water. Emphasize the overall peaceful ambiance with soft, rounded nail shapes to complete the look.
