Create a design for coffin-shaped French tip nails that blends elegance with a hint of modern flair. Picture a base of glossy pastel pink, accentuating the subtle curve of the tips. Embellish the tips with a delicate pearl white, while adding intricate silver foil detailing for a touch of sophistication. Integrate tiny rhinestones at the base of each nail to catch the light, harmoniously complementing the design. The overall look should be timeless yet playful, exuding both grace and charm.
