Congratulations you have the ideal face shape!! :)
You can wear almost any hairstyle unless there are other considerations, such as eyeglasses...
You can wear short, medium and long hair styles. Your face shape is well "balanced", or in even proportion. You will look best when hair is off your face. Most oval face shapes can wear slicked-backed looks.
Hair styles that cover up your "perfect" features with heavy bangs, or too forward-directed styles.
In wearing your hair style on your face, you'll lose your face shape behind the hair. This may appear to add weight to your face.
