Shade: Super-hot white.
Choose it: We don’t know how they did it, but Illamasqua has managed to bottle up a flame so white-hot it flickers with blue undertones. It’s as striking on a girl with streamlined style as it is on a free spirit. And bonus (or three): it goes on easy, doesn’t chip for days, and dries quickly. “It’s a clean way to make your nails pop without having to commit to a crazy bright,” manicurist Aggie Zaro says. “My favorite way to wear white is with ripped jean shorts, a white t-shirt, sandals and tons of gold bangles and skinny gold rings.”
