. Eye contact is the best and easiest thing you can do to start flirting. You can look deeply into the person's eyes while also taking the time to break eye contact to keep things from getting too intense. Consider using it in these ways:  Get caught looking.

Slow, languid smiles are generally considered sexy. Smile when you make eye contact. If you're suddenly looking into someone's eyes, toss in a smile for extra appeal. (If it's a genuine smile, the other person will see it without even looking at your mouth — it will crinkle your eyes, and is known as a Duchenne smile.) Try smiling with your eyes, not just your mouth. Make your whole face light up when you smile. Introduce yourself — or maintain the mystery (optional).
