Here are some body language tips for using your body to communicate from a distance:

1. Smile! It makes you look pretty.
2. Primp. Play with your haor and smooth your clothing as if to say "Look at me! I'm ready for male attention."
3. Stand tall. Good posture makes you look confident, and men love a confident woman.
4. Glance. Enjoy brief eye contact with a man before slowly looking away. 
5. Expose. Show off your wrists and neck because they are traditional erogenous zones.
6. Tilt. Tilt your head because this sends the message you are interested.

Here are some body language tips for using your body to communicate from close-up:

1. Nod. When he's talking, look interested in what he is saying.
2. Touch. Touch him lightly on his arm or shoulder to make a point, but don't linger.
3. Whisper. Get close to whisper something, then pull away, look him in the eyes briefly and smile.

Now, here are some gestures you should always try to avoid:

1. Crossed arms or legs. Don't cross your arms in front of your body or stand with your legs crossed as this signals you are not approachable.
2. Slouching. Poor posture and slouching shoulders demonstrates low self-esteem, which is the opposite of what most men want.
3. Hidden hands. Hands in your pockets means you might be hiding something.
4. Nose touching. Don't touch your nose. It's the telltale sign of a liar!
5. Too close. Don't invade his personal space before you know he is interested, so he doesn't feel crowded.
