The term "face shape" refers to the overall contours and features that make up a person's face. It can be used to describe various aspects such as the distance between the eyes, nose, mouth or chin, cheekbones, jawline, and other facial characteristics. Face shapes are often categorized into different types, including round, oval, square, heart-shaped, diamond, and oblong, among others. These classifications can help determine what hairstyles, makeup techniques or accessories may best complement a person's features for an overall balanced look.
