Like a stiletto heel, the stiletto nail shape is long and pointy. It helps elongate the fingers and it's synonymous with sexy. Celebrities like Fergie and Rihanna rock a more feminine version that's slightly rounder at the corners and painted in pastels. Gaga has them too, but wears a fiercer version with a sharp tip and painted in bright orange or red. Whatever version of this nail you choose, people are sure to notice.
