The First Flirt.
You must be well presented. Dress pants and an untucked button up will make you seem important and mysterious. Make sure you're:
Shave: A must, unless some females like the rogue look.
Cologne: Must be worn, and not extensively.
Hair: To what suits you, if you don't know ask some mates girlfriend to help you, and trust me she will know.
Hygiene: A must do, Have a shower or bath. No female likes her man dirty unless he comes home from work or from in bed.

Simple Tips:
If a female takes the courage to face you face to face, talk to her. You might be surprised how much you have in common.
If she's sucking the stick of her martini, she either a) is bored. b) Might want you for a quickie before she goes and finds her next victim.
Ask questions about her, she may not show it but if you talk about yourself the whole time, she most defiantly won't come back.
Brush your teeth, No Female likes a guy with smelly breath or black/yellow/green teeth.
Seem tough, sensitive and caring. If you have that then the next tips will be easy.
Talk to her, make her seem cared about; she'll be putty in your hands in no time.
Do not kiss her or touch her in anyway except hold her hand, if need be, hug her goodbye when done talking.
If you want her... and did all the talking well slip her your number on a tissue or napkin. If she likes you look out for her number.
