Fourth of July festivities are just around the corner, and our favorite summer holiday is the perfect excuse to experiment with bold color, holographic shine, and star-shaped glitter (or a firework-worthy combo of all three). Reflecting the holiday's lively spirit, many brands are releasing sparkle-laced lacquers, confetti topcoats, and mesmerizing metallics which can be layered over cream polishes for a fun, textured effect. Warning: sparks will fly.
