For an audacious and fierce baddie nail design, envision long, tapered coffin-shaped nails with a glossy black base coat. Add hints of metallic gold and deep burgundy accents, blending abstract geometric shapes with intricate linework to create a bold, eye-catching pattern. Adorn a couple of nails with tiny rhinestones or chains to enhance the luxurious vibe and complete the look with a high-shine topcoat. The overall effect should emanate confidence and a fearless attitude, turning heads wherever you go.
