Which of the following describes a hairstyle that gives the illusion of length for a square face?

A hairstyle that gives the illusion of length for a square face emphasizes verticality and softness to counterbalance the angles of the face. Long, straight hairstyles are particularly effective in achieving this goal, as they add height and elongate the face shape. The smooth lines of a long, straight hairstyle draw the eye downward, creating an impression of elongation, which is beneficial for square faces that typically have a strong jawline and equal width across the forehead.

In contrast, short layers and puffed hairstyles can contribute to a wider appearance, which may highlight the squareness of the face rather than soften it. Choppy bangs tend to emphasize the width of the forehead and the face itself, which could also work against the goal of achieving a more elongated look. Overall, long, straight hairstyles are the most suitable choice for adding an illusion of length to a square face.
