Kate Middleton-Princess of Wales-has long been admired for her poise and approachable demeanor during public engagements.

However, an expert has recently decoded one of her key body language gestures that she frequently uses to exude confidence-touching her hair. According to body language expert Judi James, Middleton’s habitual act of gently touching her hair before meeting with others serves dual purposes. While the Princess is often seen engaging with the public with a warm smile and animated gestures, it is the seemingly subtle act of hair-checking that reveals much about her approach to royal appearances.

Speaking to Fabulous, James explained that the Princess’s flowing locks, radiant smile, and open body language are carefully curated to give off an impression of warmth and confidence. “Her hair check is not just a casual gesture,” James said. “It serves two main functions. The first is a psychological tool for ingratiation. Second function of this ritual, James notes, is a personal reassurance tactic.
