While any face shape can suit a pixie cut—it's all about getting the right pixie. Typically, if you have an oval face shape, you can get away with just about any pixie haircut, whereas if you want a pixie cut for a round face, an angled bang can help give you a more balanced look.
How do I know if a pixie cut will suit me?
Look for a broad, strong jaw and chin as evidence of a square or rectangular face. Your face is square-shaped if your jaw is the widest part of your face. You have a strong, square jawline and your face is wider than it is long. However, if your face is longer than it is wide, you have a rectangular-shaped face.
What face shape best suits a pixie cut?
Almost all pixie hairstyles look great on oval, square, and heart-shaped faces. This particular style looks great on round face shapes because it provides angles, which visually soften the face's roundness.
