In body-language psychology, crossing the legs can sometimes signal:
Relaxation in a comfortable environment
Confidence or elegance in social situations
A way of maintaining personal space
4. A Sign of Protection or Shyness
In some situations, crossing the legs may also act as a subconscious protective posture. When someone feels shy, nervous, or slightly uncomfortable, they may close their posture by crossing their legs or arms.
5. Cultural Influence
Different cultures have different expectations about posture. In many societies, women crossing their legs is considered socially acceptable or refined, which reinforces the habit.
Interesting Fact 
Studies on body language suggest that people who feel safe and relaxed tend to adopt natural postures like leaning back or crossing their legs casually. However, body language always depends on the situation and personality, so it shouldn’t be interpreted in only one way.
Many experts say posture can reveal a lot about confidence, mood, and comfort level during conversations.
