They can glow in the dark, guide an airplane in to it's appropriate terminal, and spiff up a boring outfit all in one. Aw yeah, neon nail polish. Once you start, you can't stop. Pinks and neutrals will feel as hip as Layne Bryant.
Milani at CVS or any drugstore has an awesome neon pink and orange for under $5. Just use a neutral color as the base coat and it'll pop.
