Finding the right black nail polish can be tricky. A chipping black manicure is a beauty no-no that no one wants to be caught wearing, so a long-lasting formula is paramount—as is a glamorous sheen. If you favor a satiny black look, try Chanel Le Vernis Nail Colour in black satin ($26). The formula’s staying power is unparalleled, and we love the way the color catches the light. Another favorite is the limited edition No. 6 Terriblement Noir duo by Yves Saint Laurent ($30), which was inspired by a smoking tuxedo jacket. The idea is to create a tone-on-tone French manicure, using the matte shade for the base and the shinier shade for the tips.
