Fresh.

In this classic woman's opinion, there's nothing more sexy, smart and downright pleasant than smelling clean. The perfect fragrance would likely have light, refreshing notes of citrus, cucumber or white musk combined with a light balance of fruity or floral scents. The result? Pretty close to freshly laundered, sun-dried cotton.

Try Chanel Cristalle, $70, or Marc Jacobs Splash Cucumber, $65.
