While nail art feels like a beauty trend of the 21st century, it's actually inspired by a retro look. Seriously! When nail lacquer first hit mainstream America in the 1920s, the preferred way to sport glossy red polish was in the form of a moon manicure that showed a hint of the nail at the base. Current takes on the half moon feature contrasting color combinations, but paying homage to the original style is a whole lot easier since you only need one shade of polish. Read on to see how to create a modern take on one of the earliest nail art designs. Plus, watch our tutorial which uses another nifty tool to create this retro style.
