Create a luxurious and modern nail design that showcases coffin-shaped nails with a twist on the classic French tip style. Envision each nail as a canvas where the base of soft pastel hues smoothly transitions into bold, geometric angled white tips. Accentuate with delicate metallic lines or dainty rhinestone accents along the edges, reflecting a blend of elegance and contemporary flair. Ideal for a sophisticated yet trend-forward look, this design embodies class and innovation.
