Flirty body language can include subtle movements and gestures that convey interest and attraction. One common sign is prolonged eye contact, where someone holds your gaze longer than normal. Another sign is mirroring, where they mimic your movements and posture. Physical touches, such as light touches or a gentle brush of the arm, can also be a sign of flirting. Finally, leaning in toward you and maintaining proximity can signal that someone is interested in getting closer to you.
