Kim Vo, celebrity hairstylist (think Terri Hatcher and Goldie Hawn) and a frequent commentator on the E! channel, gives his picks on hairstyles that work with the subtleties of your face. 

Deepset Eyes
Do you have deepset small eyes?  Wear your bangs to the side to accentuate the curves of the eyes and to open your face.

Prominent Forehead
Do you have a prominent forehead like Christina Ricci?  Wear your bangs right above the eyes to create a softer look.

Small (Cute) Ears
Do you have small cute ears like Kate Hudson?  Allow hair to slightly cover the ears to create a sophisticated look.
