Locking eyes with your date can effectively reveal interest, emotions and desire. In addition, David Givens, director of the Center for Nonverbal Studies, points out that eye contact is a form of respect, as well as appreciation and understanding. If you notice her pupils growing larger as your conversation progresses, that means she is experiencing something that she enjoys. Also notice where her gaze is directed. If she has no problem looking into your eyes while talking, then she could be romantically interested. If her line of sight is off to the side or over your head, she may not be comfortable or ready to open up to you.

Tilting of the head is another tell-tale sign of attraction. When having a meaningful conversation, if you notice that your date has angled her head slightly while you are speaking, it means she is interested in what is being said. Vanessa Van Edwards, an author and behavioral investigator, says that exposing the neck allows pheromones to be released into the air. Pheromones are an odor agent secreted by a member of a species that is believed to attract members of the same species. Tonya Reiman, author of "The Body Language of Dating," suggests that when a woman tilts her head it is a sign she is open to attention and trusts that the other person won't hurt her.

Imitation is the highest form of flattery. If your date feels comfortable enough around you, you may notice she is mirroring some of your mannerisms or movements. For instance, if you stretch your arms up, she may do the same. If you cross your legs during a conversation, she might move to do so as well. Her inflection, sentence structure and facial expressions are other attributes that you may notice line up with yours as well. Givens notes that this type of courtship is a fine example of couples becoming at ease with each other.

If you shake your date's hand and notice that it feels damp and sweaty, it may be possible that an attraction is brewing. Moist palms are a physiological response to romantic feelings. Just as the heart beats faster when in close proximity to a crush, those same chemicals also kick-start the glands responsible for sweating. A human being's palm is made up of 370 sweat glands every square centimeter, so the more adrenaline-ridden you are, the more slick the hand will be. To be sure that your date really likes you and doesn't just have issues with her sweat glands, take note of whether she is displaying any other signs of nonverbal romantic attraction, as well.
