Many people forget these things when they're spitting game and I've noticed that as I've improved in these categories the amount of long-stares and approaches from attractive women that I've recieved has gone up dramatically. All three of these things are indicators women use to gauge your self-confidence and if your body language isn't up to par, it doesn't really matter what you say to them.

Posture: Make sure to keep your back straight, head up, and chest out as much as possible. Doing deadlifts/powercleans will help you maintain your posture. Walk like you have a purpose. Generally you want to appear as 'open' as possible. No arm crossing. No hands in your pockets. Think of your chest as an area that your hands stay away from.

Be 'Active': Gesture when talking. Bob your head when listening to music. Sway. Lean back in your chair. Tap your feet. Keep your head up. Smile to yourself. Take in your surroundings and try to make eye contact with everyone nearby at least once. Be expressive when talking to people.

Dress well: I can't stress this one enough, a sense of real style will earn you a lot of respect from women and it will make you stand out. It will also make you feel better about yourself.
