No manicure says classic glamour quite like a half-moon design, but most of us don't have the time to get the ovals perfectly precise. That's where Ruffian's collaboration with MAC comes in. The fashion duo has partnered with the makeup giant before, but this time, the endeavor extends to three sets of ready-to-go manicures. Each set ($25) has 24 preglued, presized nails with tips and moons created by designers Brian Wolk and Claude Morais. Sure, you could break out the nail art kit and create a half-moon look on your own (here's how). And you could always re-create the Spring 2011 runway manicure that inspired these premade nails. But if you're looking for flawless results in a fraction of the time, why would you go any other way?
