Diamond shape attributes: Small chin and forehead, prominent cheekbones and narrow appearance (Editor's note: Concerned that you never see "diamond" shape listed in other articles? Don't freak. You can follow "oval" advice since your face is most closely related to that shape.)
Hairstyles that work: Like oval faces, most any style works with a diamond-shaped face, but long, sweeping bangs like Ashley Greene's work well to offset any harsh angles.
Hairstyles to avoid: Stay away from any style that has volume on the sides or on the top -- this will only serve to make your face seem longer.

Face Shapes: Makeup for Diamond Faces
Makeup mission: To make your face seem more evenly proportioned.
Makeup dos: To make your face seem less long, apply blush or bronzer above your brow bones and under the tip of your chin. Also, pale lips, as seen on Nicole Kidman, will help to add some width to your face.
Makeup don't: Avoid contouring your cheekbones with blush applied in straight lines underneath them. Swirl color onto the apples of your cheeks instead to help round out your face.

Face Shapes: Hairstyles for Rectangle/Oblong Faces
Rectangle attributes: Long and thin, pointy chin, angular features and high forehead. (Editor's note: Concerned that you never see "rectangle" or "oblong" shape listed in other articles? Don't freak. You can follow "oval" advice since your face is most closely related to that shape.)
Hairstyles that work: Long, brow-skimming bangs like and chin-length bobs or layers, as shown on Liv Tyler, work well on rectangular faces because they give the illusion of width.
Hairstyles to avoid: Styles that rely on a middle part or that add height, are not suited to rectangular faces.

Face Shapes: Makeup for Rectangle/Oblong Faces
Makeup mission: To make your face seem less long.
Makeup dos: To minimize your forehead and chin, you want to play up the middle section of your rectangular face like Joan Smalls shows here. Apply blush under your cheekbones and blend out towards your ears and up to your temples. You can further downplay your lower face by applying the same blush on the underside of your jawbone and adding a dusting of highlighting powder to the center of your forehead and chin.
Makeup don't: You may want to think twice about drawing attention to the lower half of your face with bright lip colors and opt, instead, for a more neutral hue.

Face Shapes: Hairstyles for Square Faces
Square shape attributes: Proportional width and length, broad jaw line and forehead
Hairstyles that work: Long layers and wispy bangs will soften your facial angles as will an off-center part like Sandra Bullock's.
Hairstyles to avoid: Steer well clear of heavy, straight bangs and anything that has a lot of height at the crown, which will only emphasize the square angles of your face.
