The best way to introduce seductive techniques into a situation is eye contact. To start trying to be seductive, lock eyes with the person you're trying to attract. Hold their gaze to get their attention.  If the person walks over to begin a conversation, maintain eye contact as you talk. People are attracted to those who pay attention to them. Holding someone's gaze can help them feel special, making you come off as seductive. Do not hold eye contact for more than a few seconds if someone is not in conversation with you. You do not want to look like you're staring. Certain facial expressions are read as more seductive than others. When trying to attract someone,  subtlety is key in your facial expression. Instead of beaming at the other person, add a small, sly smile. Holding a person's gaze while offering a close-mouthed smile will come off as highly seductive. Posture can convey interest, which is a seductive quality. Closing your body off by crossing your arms or looking away can convey a lack of interest. Instead, work on maintaining an open posture to show the person you're interested in them.  Face the person when they're talking. Keep your arms away from your chest. Do not put anything, like a purse or bag, on your lap. Lean slightly forward. This conveys a genuine interest in the other person, which can be a seductive quality. If the person seems open to your flirtation, introduce light touch. Touch can trigger sexual interest. Do not overdo it. Stick to light, subtle touches.  For example, gently brush the person's arm or wrist during a conversation. If seated, try brushing the person's knees under the table. Pay attention to the tone you're using when talking. Speak in a soft and pleasant voice. Avoid raising your voice or talking too loud. This can come as angry, and can dampen someone's interest in you.
