Right in line with the "sexy, curvy" nail shape Langston mentioned is the wavy nail art trend. "The organic swerves add interest to your fingertips and elongate your hands," she said. "It's basically goof-proof because the waves should just flow. Every wave doesn't have to be the exact same, so just start at the upper left-hand corner of your nail and sweep the brush down, curving as you go."
