A flattering hairstyle known as "bobbed hair for round faces" refers to a hair length that falls between the chin and shoulders, creating a complementary shape for those with round facial features, such as actress Michelle Williams.
This haircut accentuates the cheekbones and jawline, creating an elongated effect that balances the roundness of the face. Historically, the bob gained popularity in the 1920s as women sought more modern and manageable hairstyles.
